"My G.o.d," sobbed the old man"s voice, "my G.o.d, the pit of six thousand stairs! It is Lammas-tide, the night of sacrifice-dear G.o.d, dear G.o.d save me! Ia! Ia! Shub-Niggurath! It waits for us, waits for us, the Goat With Ten Thousand Young!" Shub-Niggurath! It waits for us, waits for us, the Goat With Ten Thousand Young!"
I crawled across an uneven floor, wet and slimy, and the smells around me were the scents of deep earth, dripping rock, and far off the terrible fetors of still worse things: corruption, charred flesh, and the sickeningly familiar scent of incense. My hands touched my companion in this darkness and he pulled away: "No, never! Fiends, that you used poor Judith as bait, to bring me to you! The Hooded Thing in the darkness taught you how, as it taught others before you-showed you the pa.s.sages in the Book of Eibon Book of Eibon-told you how to take the bodies of others, how to leave their minds trapped in your old and dying body... the body that you then sacrificed to them! A new body, a strong body, a man"s body, healthy and fit... ."
"Hush," I whispered, "hush, you are raving! Who are you, where is this?" Again I touched his hands, and felt the stick-like bones and flaccid, silky flesh of a very old man. At the same moment those frail hands fumbled at my face, my shoulders in the dark, and he cried out: "Get away from me! You weren"t good enough for him, twisted and crippled and weak! And your daughter only a woman, without the power of a man! It was all a trap, wasn"t it? A trap to lure me, thinking it was she she who sent for me to set her free... ." His thin voice rose to a shriek and he thrust me from him with feeble hysteria. "And now you will send me down to the pit, down to the pit of the shuggoths!" As his sobs changed to thin, giggling laughter I heard a stirring, far away in the darkness; a soughing, as if of the movement of things infinitely huge, and soft. who sent for me to set her free... ." His thin voice rose to a shriek and he thrust me from him with feeble hysteria. "And now you will send me down to the pit, down to the pit of the shuggoths!" As his sobs changed to thin, giggling laughter I heard a stirring, far away in the darkness; a soughing, as if of the movement of things infinitely huge, and soft.
I staggered to my feet, my legs responding queerly; I reeled and limped like a drunken man. I followed the wall in darkness, feeling it to be in places ancient stones set without mortar, and in others the naked rock of the hill itself. There was a door, desiccated wood strapped with iron that grated, rusty and harsh, under my hands. I stumbled back into the darkness, and struck against something-a stone table, pitted with ancient carvings-and beside it found the only means of egress, a square opening in the floor, in which a flight of worn, shallow steps led downwards.
Gropingly I descended, hands outstretched on either side to feel the wet rock of the wall that sometimes narrowed to the straightest of seams: terrified of what might lie below me, yet I feared to be in the power of the madmen I knew to be above. I was dizzy, panting, my mind prey to a thousand illusions, the most terrifying of which was that of the sounds that I seemed to hear, not above me, but below.
In time the darkness glowed with thin smears of blue phosphor, illuminating the abyss below me. Far down I could descry a chamber, a sort of high-roofed cave where the niter dripped from the walls and showed up a crumbling stone altar, ruinously ancient and stained black with horrible corruption. There was an obscene aberration to the entire geometry of the chamber, as if the angles of floor and walls should not have met in the fashion they appeared to; as if I viewed an optical illusion, a trick of darkness and shadow. From the innermost angle of that chamber darkness issued, like a thicker flow of night, blackness that seemed one moment to congeal into discrete forms which the next proved to be only inchoate stirrings. Yet there was something there, something the fear of which kept me from moving on, from making a sound-from breathing, even, lest the gasp of my breath bring upon me some unimaginably nightmarish fate.
My fellow captive"s high, hysterical giggling on the stair above me drove me into a niche in the wet rock. He was coming down-and he was not alone. Pressed into the narrow darkness I only heard the sounds of bodies pa.s.sing on the stair. A moment later others followed them, while I crouched, praying to all the G.o.ds ever worshipped by fearful man to be spared the notice of anything that walked that eldritch abyss. At the same moment sounds rose from below, a rhythmless wailing or chittering that nevertheless seemed to hold the form of music, underlain by a thick lapping or surging sound, as if of thick, unspeakably vile liquid rising among stones.
Looking around the sheltering coign of rock, I saw by the growing purplish h.e.l.l-glare below me the tall figure of Burnwell Colby, standing beside the altar, an unfleshed skull held upraised in his hands. Darkness ringed him, but it seemed almost as if the skull itself gave light, a pulsing and horrible radiation that showed me-almost-the shapes of which the utter blackness was comprised. I bit my hand to keep from crying out, and wondered that the pain of it did not wake me; an old man lay on the altar, and by his sobbing giggles I knew him to be he who had been shut into the stone crypt above with me. Colby"s deep voice rang out above the strident piping: "Ygnaiih... ygnaiih ygnaiih... thflthkh"ngha... thflthkh"ngha... ." ."
And the things in the darkness-horrible half-seen suggestions of squamous, eyeless heads, of tentacles glistening and of small round mouths opening and closing with an appalling glint of teeth-answered with a thick and greedy wail.
"H"ehye n"grkdl"lh n"grkdl"lh, h"ehye h"ehye... in the name of Yog-Sothoth I call, I command... ."
Something-I know not what nor do I dare to think-raised itself behind the altar, something shapeless that glowed and yet seemed to swallow all light, hooded in utter darkness. The old man on the altar began to scream, a high thin steady shriek of absolute terror, and Colby shouted, "I command you... I command... !" Then it seemed to me that he gasped, and swallowed, as if his breath stopped within his lungs, before he held up the skull again and cried, "N"grkdl"lh y"bthnk y"bthnk, Shub-Niggurath! In the name of the Goat With Ten Thousand Young I command!"
Then the darkness swallowed the altar, and where a moment before I could see the old man writhing there I could see only churning darkness, while a hideous fetor of blood and death rolled up from the pit, nearly making me faint. "Before the Five Hundred," cried Colby... then he staggered suddenly, nearly dropping the skull he held. "Before the Five Hundred... ."
He gasped, as if struggling to speak. The thing upon the altar lifted its hooded head, and in the sudden silence the dreadful lapping sound of the deeper darkness seemed to fill the unholy place, and the far-off answering echo of the now-silenced pipes.
Then with a cry Colby fell to his knees, the skull slipping from his hands. He choked, grasping for it, and from the darkness of the stair behind him another form darted forward, small and slim, and stooped to s.n.a.t.c.h up the talisman skull of the terrible ancestor who had ruled this place.
"Ygnaiih, ygnaiih ygnaiih Yog-Sothoth!" cried a woman"s voice, high and powerful, filling the hideous chamber, and the darkness that had surged forward toward her seemed for a moment to close in as it had closed around the old man on the altar, then to fall back. By the queer, actinic luminosity of the skull I could see the woman"s face, and recognized her as Judith Delapore, niece and granddaughter of the madmen who ruled Depewatch. Yet how different from the sweet countenance painted on Colby"s miniature! Like the ivory mask of a G.o.ddess, cold and lined with concentration, she bent her eyes on the heaving swirl of nightmare that surrounded her, not even glancing at her lover, who lay gasping, twisting in convulsions at her feet. In a high, hard voice she repeated the dreadful words of the incantations, and neither flinched nor wavered as the dreadful things flittered and crawled and bounced in the darkness.

In a high, hard voice she repeated the dreadful words of the incantations, and neither flinched nor wavered as the dreadful things flittered and crawled and bounced in the darkness.
Only when the hideous rite was ended, and the unspeakable congregation had trickled away through the blasphemous angle of the inner walls, did the young woman lower the skull she held. She stood in her black gown, outlined in the gleam of the niter on the walls, staring into the abyss from which those dreadful unhuman things had come, barely seeming to notice me as I stumbled and staggered down the last of the stairs.
Of the old man"s body that had lain upon the altar nothing whatsoever remained. A thick layer of slime covered the stone and ran down onto the floor, which was perhaps half an inch deep in a brownish liquid that glistened in the feeble blue gleam of the niter. Having seen Burnwell Colby engulfed by that wriggling darkness I staggered to where he had lain with some confused idea of helping him, but as I dropped to my knees I saw that only a lumpy ma.s.s of half-dissolved flesh and bones remained. The bones themselves had the appearance of being charred, almost melted. I looked up in horror at the woman with the skull and her eyes met mine, clear golden hazel, like other eyes I could not quite recall. Her eyes widened and filled with anger and hate: "You," she whispered. "So you did not take him after all?"
I only shook my head, her words making no sense to me in my shaken state, and she went on, "As you have seen, Uncle, it is I, now, and not Grandfather-Grandfather who has not existed for over fifty years-who rules now here." And to my horror she held out her hand toward that hideously anomalous angle of the walls where the darkness lay waiting. "Y"bfnk-ng"haiie... ."
I cried out. At the same instant light blazed up on the stairway that led to the upper and innocent realms of the ignorant world: blue-white incandescence, like lightning, and the crackle of ozone filled the reeking air.
"My dear Miss Delapore," said Holmes, "if you will pardon my interruption, I fear you are laboring under a misapprehension." He came down the last of the stair, bearing in one hand a metal rod, from which a flickering corona of electricity seemed to sparkle, flowing back to a similar rod held up by Carnaki, who followed him down the stair. Carnaki wore a sort of pack or rucksack upon his back, of the kind one sees porters in Constantinople carrying; a dozen wires joined it to the rod in his hand, and lightnings leaped from that rod to Holmes", seeming to surround the two men in a deadly nimbus of light. The cold glare blanched all color from his face, so that his eyebrows stood out nearly black, like a man who has received a mortal blow and bleeds within.
Looking down at me he asked, as if we shared a cup of tea at Baker Street, "What was your wife"s favorite flower?"
Miss Delapore, startled, opened her mouth to speak, but I cried in a convulsion of grief: "How can you ask that, Holmes? How can you speak of my Mary in this place, after what we have seen? Her life was all goodness, all joy, and it was for nothing nothing, do you understand? If this-this blasphemy-this monstrous abyss underlies all of our world, how can any good, any joy exist in safety? It is a mockery-love, care, tenderness... it means nothing, and we are all fools for believing in any of it... ."
"Watson!" thundered Holmes, and again Miss Delapore turned her eyes to him in astonishment.
"Watson?" she whispered.
His gaze held mine, and he asked again: "What was Mrs. Watson"s favorite flower?"
"Lily of the valley," I said, and buried my face in my hands. Even as I did so I saw-such was the horror and strangeness of my dream-that they were the hands of an elderly man, thin and twisted with arthritis, and the wedding-band that I had never ceased to wear with my Mary"s death was gone. "But none of it matters now, nor ever will again, knowing what I now know of the true nature of this world."
Through my weeping I heard Carnaki say softly, "We"ll have to switch off the electrical field. I don"t think we can get him up the stairs."
"You will be safe," said Miss Delapore"s voice. "I command Them now-as did my grandfather, or the thing that for so many years pa.s.sed itself off as my grandfather. I knew his goal-its goal-was to take over Burnwell"s body, as it had taken over my grandfather"s fifty years ago. He despised my uncle, as he despised my father, and as he despised me as a woman, thinking us all too weak to withstand the power raised by the Rite of the Book of Eibon Book of Eibon. Why else did he bring me home from school, save to lure that poor American to his fate?"
"With a letter blotted with tears," said Holmes drily. "Even in the margins, and the blank upper portion by the address. Hardly the places where a girl"s tears would fall while writing, but it"s difficult to keep drops from spattering there when they"re dipped from a bedroom pitcher with the fingers."
"Had I not written that letter," she replied, "it would be I, not Grandfather, who was given to the Hooded One tonight. At least by luring Burnwell to me I was able to give him poison-brown spider-mushroom, that does not take effect for many days. Grandfather would have had him, one way or another-he does not give up easily."
"And was it you who sent for him, to meet your grandfather in Brighton?"
"No. But I knew it would come. When Grandfather-when Lord Rupert"s vampire spirit-entered poor Burnwell"s body, that body was already dying, though none knew it but I. I knew Uncle Carstairs had mastered the technique too, of crossing from body to body-I a.s.sume it is you who were his target, and not your friend."
"Even so," said Holmes, and his voice was quiet and bitterly cold. "He underestimated me-and both underestimated you, it seems."
And there was the smallest touch of defiance in her voice as she replied, "Men do. Yourself included, it seems."
The snapping hiss of the electricity ceased. I opened my eyes to see them kneeling around me, in the horror of that nighted cavern: Holmes and Carnaki, holding their electrical rods to either of my hands, and Miss Delapore looking into my eyes. Somehow despite the darkness I could see her clearly, could see into her golden eyes, as one can in dreams. What she said to me I do not remember, lost as it was in the shock and cold when Carnaki touched the switch... .
I opened my eyes to summer morning. My head ached; when I brought my hand up to touch it, I saw that my wrists were bruised and chafed, as if I had been bound. "You were off your head for much of the night," said Holmes, sitting beside the bed. "We feared you would do yourself an injury-indeed, you gave us great cause for concern."
I looked around me at the simple wall-paper and white curtains of my bedroom at the Cross of Gold in High Clum. I stammered, "I don"t remember what happened... ."
"Fever," said Carnaki, coming into the room with a slender young lady whom I instantly recognized from the miniature Burnwell Colby had showed us as Miss Judith Delapore. "I have never seen so rapid a rise of temperature in so short a time; you must have taken quite a severe chill."
I shook my head, wondering what it was about Miss Delapore"s haggard calm, about her golden-hazel eyes, that filled me with such uneasy horror. "I remember nothing," I said. "Dreams... . Your uncle came here, I believe," I added, after Holmes had introduced the young lady. "At least... I believe it was your uncle... ." Why was I so certain that the wizened, twisted little man who had come to my room-whom I believed had come to my room-yesterday had been Carstairs Delapore? I could recall nothing of what he had said. Only his eyes... .
"It was my uncle," said Miss Delapore, and as I looked at her again I realized that she wore mourning. "You remember nothing of why he came here yesterday? For before he could mention the visit to anyone at the Priory... ." And here she glanced across at Holmes; "He fell down the stairs there, and died at the bottom."
I expressed my horrified condolences, while trying to suppress an inexplicable sense of deepest relief that I somehow a.s.sociated with dreams I had had while delirious. After inclining her head in thanks, Miss Delapore turned to Holmes, and held out to him a box of stout red cardboard, tied up with string. "As I promised," she said.
I lay back, overcome again by a terrible exhaustion-as much of the spirit, it seemed, as of the body. While Carnaki prepared a sedative draught for me Holmes walked Miss Delapore out to our mutual parlor, and I heard the outer door open.
"I have heard much of your deductive abilities, Mr. Holmes," said the young woman"s voice, barely heard through the half-open bedroom door. "How did you know that my uncle, who must have come here to take you as my grandfather took Burnwell, had seized upon your friend instead?"
"There was no deduction necessary, Miss Delapore," said Holmes. "I know Watson-and I know what I have heard of your uncle. Would Carstairs Delapore have come down into danger, to see what he could do for an injured man?"
"Do not think ill of my family, Mr. Holmes," said Miss Delapore, after a time of silence. "The way which leads down the six thousand stairs cannot be sealed. It must always have a guardian. That is the nature of such things. And it is always easier to find a venal successor who is willing to trade to Them the things They want-the blood They crave-in exchange for gifts and services, than to find one willing to serve a lonely guardianship solely that the world above may remain safe. They feared Lord Rupert-if the thing that all knew as Lord Rupert was in fact not some older spirit still. His bones, buried in the sub-crypt, shall, I hope, prove a barrier that They are unwilling to cross. Now that the skull, which was the talisman that commanded Their favors, is gone, perhaps there will be less temptation among those who study in the house."
"There is always temptation, Miss Delapore," said Holmes.
"Get thee behind me, Mr. Holmes," replied the woman"s voice, with a touch of silvery amus.e.m.e.nt far beyond her years. "I saw what that temptation did to my uncle, in his desperate craving to s.n.a.t.c.h the rule of the things from my grandfather. I saw what my grandfather became. These are things I shall remember, when the time comes to seek a disciple of my own."
I was drowsing already from Carnaki"s draught when Holmes returned to the bedroom. "Did you speak to Colby?" I asked, struggling to keep my eyes open as he went to the table and picked up the red cardboard box. "Is he all right?" For my dreams as to his fate had been foul, terrible, and equivocal. "Warn him... prevent the old Viscount from doing harm?"
Holmes hesitated for a long time, looking down at me with a concern that I did not quite understand in his eyes. "I did," he replied at length. "To such effect that Viscount Gaius has disappeared from the district-for good, one hopes. But as for Burnwell, he too has... departed. I fear that Miss Delapore is destined to lead a rather difficult and lonely life."
He glanced across at Carnaki, who was packing up what appeared to be an electrical battery and an array of steel rods and wires into a rucksack, the purpose of which I could not imagine. Their eyes met. Then Carnaki nodded, very slightly, as if approving what Holmes had said.
"Because of what was revealed," I asked, stifling a terrible yawn, "about this... this blackmail that was being practiced? The young hound, to desert a young lady like that." My eyelids slipped closed. I fought them open again, seized by sudden panic, by the terror that I might slide into sleep and find myself again in that dreadful abyss, watching the horrible things that fluttered and crept from those angles of darkness that should not have been there. "Did you learn... anything of these studies they practiced?"
"Indeed we did," said Carnaki. And then, a little airily, "There was nothing in them, though."
"What did Miss Delapore bring you, then?"
"Merely a memento of the case," said Holmes. "As for young Mr. Colby, do not be too hard on him, Watson. He did the best he could, as do we all. I am not sure that he would have been entirely happy with Miss Delapore in any event. She was... much the stronger of the two."
Holmes never did elucidate for me the means by which he bridged the gap between his supposition that Viscount Delapore was engaged in kidnapping children for the purposes of some vile cult centered in Depewatch Priory, and evidence sufficient to make that evil man flee the country. If he and Carnaki found such evidence at the Priory-which I a.s.sume was the reason he had asked the young antiquarian to accompany us to Shropshire-he did not speak to me of it. Indeed, he showed a great reluctance to refer to the case at all.
For this I was grateful. The effects of the fever I had caught were slow to leave me, and even as much as three years later I found myself prey to the sense that I had learned-and mercifully forgotten-something that would utterly destroy all my sense of what the world is and should be; that would make either life or sanity impossible, if it should turn out to be true.
Only once did Holmes mention the affair, some years later, during a conversation on Freud"s theories of insanity, when he spoke in pa.s.sing of the old Viscount Delapore"s conviction-evidently held by others in what is now termed a folie a deux folie a deux-that the old man had in fact been the reincarnated or astrally transposed spirit of Lord Rupert Grimsley, once Lord of Depewatch Priory. And then he spoke circ.u.mspectly, watching me, as if he feared to wake my old dreams again and cause me many sleepless nights.
I can only be sorry that the case ended without firm conclusion, for it did, as Holmes promised me that night on the Embankment, show me unsuspected colors in the spectrum of human mentality and human existence. Yet this was not an unmixed blessing. For though I know that my fever-dream was no more than that-a fantastic hallucination brought on by illness and by Carnaki"s own curious monomania about otherworld cults and ancient writings-sometimes in the shadowland between sleep and waking I think of that terrible blue-lit abyss that lies beneath an old Priory on the borders of Wales, and imagine that I hear the eerie piping of chaos rising up out of blasphemous angles of night. And in my dreams I see again the enigmatic Miss Delapore, standing before the chittering congregation of nightmares, holding aloft in her hands the skull of Lord Rupert Grimsley: the skull that now reposes in a corner of Holmes" room, wrapped in its red cardboard box.

Most people know Lewis Carroll (the pen name of Charles Lutwidge Dodgson) as the author of Alice"s Adventures in Wonderland Alice"s Adventures in Wonderland. Dodgson became good friends with the family of one of his academic colleagues, the Liddells, and would often take their children along with him when he went rowing on the nearby rivers. During these expeditions he would make up fanciful tales to entertain the children, and one of the girls, Alice, was so enchanted that she begged Dodgson to write it all down. The enthusiastic reception for the ma.n.u.script by fantasy author George MacDonald and his children convinced Dodgson to pursue publication. Dodgson"s private life has been the subject of intense speculation, especially regarding his relationship with the Liddells. (Dodgson"s family apparently destroyed several pages of his diary, presumably to protect his reputation.) We know that he was tormented by feelings of guilt and shame, which apparently restrained him from following his father into the priesthood. It"s all very mysterious. One thing that"s beyond any doubt though is that Dodgson demonstrated brilliance in many different fields. Notably, he held a lectureship in mathematics, and wrote books on logic. It"s those abilities that he puts to good use in our next adventure.
It was in the fall of 1891 that I received a telegram from the Reverend Charles Dodgson, inviting me to his residence in Guildford, Surrey. It was not for a medical consultation, but of vital importance to the present trial of the Moriarty gang: the mystery of Professor Moriarty"s cipher.
Reverend Dodgson was both an author of children"s books and a mathematician. My wife was fond of the Alice books under his nom-de-plume nom-de-plume, Lewis Carroll, while Holmes once recommended me to read his Game of Logic Game of Logic to hone my a.n.a.lytical reasoning. It surprised me that Dodgson knew of the coded notebooks, as their existence had been suppressed. It was not five months ago that my friend Sherlock Holmes perished at Reichenbach Falls in his final confrontation with James Moriarty. Even in death, Holmes struck a fatal blow against Moriarty"s criminal confederates, leaving doc.u.ments that thoroughly incriminated them. Inspector Patterson invited me to examine the materials recovered from one of Moriarty"s secret lairs: vials of opiates among blueprints and handwritten musical scores; purloined paintings beside burned account books; and most intriguing, notebooks written in Moriarty"s hand, the oldest of which had a page torn out. to hone my a.n.a.lytical reasoning.

Moriarty"s notebooks contained mathematical formulae interspersed with code. Mycroft Holmes speculated it was a Vigenere cipher, but even he couldn"t solve it. "Alas, both the Kasiski and Kerckhoffs methods failed," said Mycroft. "If only we knew what the coded messages were about. Are they musings on mathematics, or something more sinister? Find the key, Watson, and we"ll glimpse Moriarty"s mind."
I was intrigued by Dodgson"s message. Did he know the key, when even Mycroft Holmes failed? I immediately dispatched a telegram accepting his invitation.
Thus I found myself in Guildford, sipping tea with Charles Dodgson in his parlour. The Reverend, a thin man with uneven blue eyes and sloped shoulders, tilted his left ear towards me as we talked.
"My condolences, Doctor Watson, on the untimely pa.s.sing of Mr. Holmes," said he. "I fear I must bear some of the burden for his demise."
"Oh? Did you know him?" I asked.
"I knew of Holmes at Oxford, though we never met. It was James Moriarty I knew, through our years at Christ Church debating mathematics and logic. Is there a volume from Moriarty"s effects, with a single coded page torn out?"
"Indeed!" I exclaimed. "How did you know?"
"Because I have that page." Dodgson retrieved a copy of Through the Looking Gla.s.s Through the Looking Gla.s.s from his collection. Tucked within was the coded page he spoke of, folded and yellowed with age. "Tenniel"s Jabberwock ill.u.s.tration always reminds me of Moriarty, hypnotic and serpentine." from his collection. Tucked within was the coded page he spoke of, folded and yellowed with age. "Tenniel"s Jabberwock ill.u.s.tration always reminds me of Moriarty, hypnotic and serpentine."
"How did you get this?"
"That, Doctor, is a twisted tale," said he. "It began with the Order of Copernicus, and ended with the tragic murder of a young prodigy named Arthur Doyle."
The Order of Copernicus is a fellowship of scholars, physicians, mathematicians and philosophers. The Copernicans often invite new members to enrich their symposia with fresh ideas and voices. Moriarty first introduced me to the Order years ago, after he completed his dissertation on the Binomial Theorem. I found their debates enthralling, and partic.i.p.ated whenever I could.
In early summer, 1879, Moriarty and I were invited to Aston by a fellow Copernican, Doctor Reginald h.o.a.re. Reginald introduced us to his young lodger, Arthur Doyle, a medical student who was working as a dispensing a.s.sistant taking house calls on Reginald"s behalf. I found him an engaging conversationalist and a sharp observer.
"What do you plan to do with your future, Arthur?" I asked.
"Surgery, sir," said Arthur. "I"m very much inspired by Doctor Bell at the Edinburgh University. But I"d also like to become a writer like you, actually, and have written some stories for Reginald"s children. Edgar Allan Poe"s another inspiration, and I"m attempting a mystery now."
"Poe! Now there was a true Copernican. I heard he was a great cryptographer," I said.
Moriarty disagreed. "He indulged in subst.i.tution codes, barely worth the effort to solve, unlike Vigenere ciphers."
Arthur asked what a Vigenere cipher was.
"It"s based on the Caesar cipher, which shifted letters by a chosen number of positions, looping back to the beginning of the alphabet if necessary," I explained. "Shift the word JABBERWOCKY four positions to the right, you"d have NEFFIVSGOC. To solve the coded message, apply the shift in reverse.
"The Vigenere cipher uses a keyword where each letter in the alphabet represented a different shift. For example, if ALICE were my keyword, that would mean shifts of 0, 11, 8, 2, and 5. The keyword is repeated as needed, and so JABBERWOCKY becomes JLJDIRHWEOY."
Moriarty nodded. "There are mathematical ways to solve a Vigenere code. Kasiski"s method determines the length of the keyword by measuring distances between repeating combinations, then uses frequency a.n.a.lysis to break the code. Kerckhoffs" method focuses on solving the keyword itself."
"Moriarty, didn"t you have a notebook at Christ Church where you jotted down your formulae?" I asked. "You used a cipher on the annotations. Was that Vigenere?"
Moriarty smiled. "It was, to ensure that the musings and errors of my youth were for my eyes alone. But I"m confident that my code cannot be broken by either the Kerckhoffs or Kasiski solutions. They a.s.sume the keyword would be short, and repeated. But if the keyword"s significantly long, like a piece of text, then a coded message would be virtually unbreakable."
"Respectfully, Professor, the keyword may be impervious to a.n.a.lysis, but the codemaker is not," said Arthur. "At medical school, Professor Bell taught us to observe the person as well as the disease in our diagnoses. By a.n.a.lyzing the man"s habits, experiences and indulgences, one can deduce the choice of text he uses for his code."
"You presume to unriddle my cipher by mere observation?" asked Moriarty.
"If I had the chance to get to know you better, Professor, I daresay I could figure out your code," said Arthur.
"I know a challenge when I hear one! Reginald, indulge me by releasing Arthur from his obligations on weekends. My university"s not far, and I will pay for travel and lodging. He may observe me in my element, while I in turn will mentor him and provide him with a sample of cipher to unriddle. If he succeeds by summer"s end, I will pay his tuition."
Moriarty had obviously taken a liking to Arthur Doyle, perhaps eager to guide a young man into his genius.
