"You shall see him later," I promised, endeavouring to calm her. "At present remain quiet. No good can possibly be done by this wild conduct."
"Where is Sir Bernard?" she inquired suddenly. "Have you telegraphed for him? I must see him."
"As soon as the office is open I shall wire."
"Yes, telegraph at the earliest moment. Tell him of the awful blow that has fallen upon us."
Presently, by dint of much persuasion, we managed to quiet her. The nurse removed her hat, helped her out of her fur-lined coat, and she sat huddled up in a big "grandfather" chair, her handsome evening gown crushed and tumbled, the flowers she had worn in her corsage on the previous night drooping and withered.
For some time she sat motionless, her chin sunk upon her breast, the picture of dejection, until, of a sudden, she roused herself, and before we were aware of her intention she had torn off her marriage ring and cast it across the room, crying wildly:
"It is finished. He is dead--dead!"
And she sank back again, among the cushions, as though exhausted by the effort.
What was pa.s.sing through her brain at that moment I wondered. Why should a repulsion of the marriage bond seize her so suddenly, and cause her to tear off the golden fetter under which she had so long chafed? There was some reason, without a doubt; but at present all was an enigma--all save one single point.
When I returned to the police to urge them not to disturb Mrs.
Courtenay, I found them a.s.sembled in the conservatory discussing an open window, by which anyone might easily have entered and left. The mystery of the kitchen door had been cleared up by Short, who admitted that after the discovery he had unlocked and unbolted it, in order to go round the outside of the house and see whether anyone was lurking in the garden.
When I was told this story I remarked that he had displayed some bravery in acting in such a manner. No man cares to face an a.s.sa.s.sin unarmed.
The man looked across at me with a curious apprehensive glance, and replied:
"I was armed, sir. I took down one of the old Indian daggers from the hall."
"Where is it now?" inquired the inspector, quickly, for at such a moment the admission that he had had a knife in his possession was sufficient to arouse a strong suspicion.
"I hung it up again, sir, before going out to call the doctor," he replied quite calmly.
"Show me which it was," I said; and he accompanied me out to the hall and pointed to a long thin knife which formed part of a trophy of antique Indian weapons.
In an instant I saw that such a knife had undoubtedly inflicted the wound in the dead man"s breast.
"So you armed yourself with this?" I remarked, taking down the knife with affected carelessness, and examining it.
"Yes, doctor. It was the first thing that came to hand. It"s sharp, for I cut myself once when cleaning it."
I tried its edge, and found it almost as keen as a razor. It was about ten inches long, and not more than half an inch broad, with a hilt of carved ivory, yellow with age, and inlaid with fine lines of silver.
Certainly a very dangerous weapon. The sheath was of purple velvet, very worn and faded.
I walked back to where the detectives were standing, and examined the blade beneath the light. It was bright, and had apparently been recently cleaned. It might have been cleaned and oil smeared upon it after the commission of the crime. Yet as far as I could discern with the naked eye there was no evidence that it had recently been used.
It was the man"s curious apprehensive glance that had first aroused my suspicion, and the admissions that he had opened the back door, and that he had been armed, both increased my mistrust. The detectives, too, were interested in the weapon, but were soon satisfied that, although a dangerous knife, it bore no stain of blood.
So I put it back in its case and replaced it. But I experienced some difficulty in getting the loop of wire back upon the bra.s.s-headed nail from which it was suspended; and it then occurred to me that Short, in the excitement of the discovery, and ordered by Ethelwynn to go at once in search of me, would not without some motive remain there, striving to return the knife to its place. Such action was unnatural.
He would probably have cast it aside and dashed out in search of a cab. Indeed, the constable on the beat had seen him rush forth hurriedly and, urged by Ethelwynn, run in the direction of Kew Bridge.
No. Somehow I could not rid myself of the suspicion that the man was lying. To my professional eye the weapon with which the wound had been inflicted was the one which he admitted had been in his possession.
The story that he had unlocked the door and gone in search of the a.s.sa.s.sin struck the inspector, as it did myself, as a distinctly lame tale.
I longed for the opening of the telegraph office, so that I might summon my friend Jevons to my aid. He revelled in mysteries, and if the present one admitted of solution I felt confident that he would solve it.
CHAPTER VIII.
AMBLER JEVONS IS INQUISITIVE.
People were about me the whole time. Hence I had no opportunity of re-examining the little object I had picked up from the spot where the murderer must have stood.
When morning dawned two detectives from Scotland Yard arrived, made notes of the circ.u.mstances, examined the open window in the conservatory, hazarded a few wise remarks, and closely scrutinised the dagger in the hall.
Ethelwynn had taken her sister to a friend in the vicinity, accompanied by the nurse and the cook. The house was now in the possession of the police, and it had already become known in the neighbourhood that old Mr. Courtenay was dead. In all probability early pa.s.sers-by, men on their way to work, had noticed a constable in uniform enter or leave, and that had excited public curiosity. I hoped that Ambler Jevons would not delay, for I intended that he should be first in the field. If ever he had had a good mystery before him this certainly was one. I knew how keen was his scent for clues, and how carefully and ingeniously he worked when a.s.sisting the police to get at the bottom of any such affair.
He came a little after nine in hot haste, having driven from Hammersmith in a hansom. I was upstairs when I heard his deep cheery voice crying to the inspector from Scotland Yard:
"Hulloa, Thorpe. What"s occurred? My friend Doctor Boyd has just wired to me."
"Murder," responded the inspector. "You"ll find the doctor somewhere about. He"ll explain it all to you. Queer case--very queer case, sir, it seems."
"Is that you, Ambler?" I called over the banisters. "Come up here."
He came up breathlessly, two steps at a time, and gripping my hand, asked:
"Who"s been murdered?"
"Old Mr. Courtenay."
"The devil!" he e.j.a.c.u.l.a.t.ed.
"A most mysterious affair," I went on. "They called me soon after three, and I came down here, only to find the poor old gentleman stone dead--stabbed to the heart."
"Let me see him," my friend said in a sharp business-like tone, which showed that he intended to lose no time in sifting the matter. He had his own peculiar methods of getting at the bottom of a mystery. He worked independently, and although he a.s.sisted the police and was therefore always welcomed by them, his efforts were always apart, and generally marked by cunning ingenuity and swift logical reasoning that were alike remarkable and marvellous.
I gave him a brief terse outline of the tragedy, and then, unlocking the door of the room where the dead man still lay in the same position as when discovered, allowed him in.
The place was in darkness, so I drew up the Venetian blinds, letting in the grey depressing light of the wintry morning.
He advanced to the bed, stood in the exact spot where I had stood, and where without doubt the murderer had stood, and folding his arms gazed straight and long upon the dead man"s features.
Then he gave vent to a kind of dissatisfied grunt, and turned down the coverlet in order to examine the wound, while I stood by his side in silence.
Suddenly he swung round on his heel, and measured the paces between the bed and the door. Then he went to the window and looked out; afterwards making a tour of the room slowly, his dark eyes searching everywhere. He did not open his lips in the presence of the dead. He only examined everything, swiftly and yet carefully, opening the door slowly and closing it just as slowly, in order to see whether it creaked or not.
It creaked when closed very slowly. The creaking was evidently what the under-housemaid had heard and believed to be the creaking of boots. The murderer, finding that it creaked, had probably closed it by degrees; hence it gave a series of creaks, which to the girl had sounded in the silence of the night like those of new boots.
