The barrister pulled out a cigar-case.
"Try one of these, Winter," he said. "You will find them soothing."
"I never smoke whilst on business," was the testy reply.
"I invariably do." He proceeded to light a cigar, which he smoked with zest.
"I do not know how it is," went on Mr. Winter, "but whenever I happen to meet you, Mr. Brett, in the course of an inquiry, I always start by being very angry with you."
"Why?" There was an amused twinkle in Brett"s eyes, which might have warned the other of a possible pitfall.
"Because you treat me as if I were a precocious youth. You listen to my theories with a sort of pitying indulgence, yet I have the reputation of being one of the best men in Scotland Yard, or I should not have been put on this job. And I am older than you, too."
"I may surely pity you," said Brett, "even if I don"t indulge you too much."
"There you go again," snapped the detective. "Now, what is there silly about my theory of the crime, I should like to know."
"You shall know, and before you are much older. Bear with me for a little while, I beg of you. You may be right, and I may be quite wrong, but I think there is much beneath the surface in the investigations we are now pursuing. My advice to you is to drop all preconceived theories, to note every circ.u.mstance, however remote it may appear in its bearing upon events, and in any case not to act precipitately. Whatever you do, don"t arrest anybody."
"But," said the other, somewhat mollified by Brett"s earnestness, "half a dozen people may be arrested at any moment."
"Pray tell me how?"
"Descriptions of the stolen diamonds and of the suspected persons are in every police office in Great Britain and in most Continental centres by this time. Pa.s.sengers by all steamers are most carefully scrutinised.
Every p.a.w.nbroker and diamond merchant in the country is on the look-out, and, generally speaking, it will be odd if somebody does not drop into the net before many hours have pa.s.sed."
"It will, indeed," murmured Brett; "and no doubt the somebody in question will experience a certain amount of inconvenience before he proves to you that he had nothing whatever to do with the matter. Now, don"t answer me, Winter, but ponder seriously over this question: Do you really think that the intelligence which planned and successfully carried through an operation of such magnitude will be trapped by plain-clothes constables watching the gangways of steamships, or by any p.a.w.nbroker who has ever lent half the value of a pledge?"
Almost impatiently the barrister waved the subject out of the hansom, and the detective had sense enough to leave him alone during the few remaining minutes before the vehicle pulled up near the Albert Gate mansion.
Brett stopped the driver some little distance short of the house itself, as he did not wish to attract the attention of a knot of curious sightseers in the street. He asked Winter to precede him and make known the fact that he was coming, so that there would be no delay at the door. This the detective readily agreed to, and Brett rapidly took in the main external features of the house which had become the scene of such a remarkable tragedy.
It was a palatial structure, built on the sombre lines of the Early Victorian period. Miss Talbot"s brief description of the measures taken to protect its occupants from interference was fully borne out by its aspect. There was no access to the bas.e.m.e.nt; the main entrance was situated at the side; all the ground-floor and first-storey windows facing into the street were fitted with immovable wooden venetians.
Presumably those on the Park side were similarly secured, whilst the back wall ab.u.t.ted on to that of another mansion, equally large and strongly built, tenanted by a well-known peer.
Truly, it required a genius almost unrivalled in the annals of crime to murder four people and steal diamonds worth millions in such a place whilst guarded by twelve London policemen and under the special protection of the Home Office.
The appearance of Winter at the door caused the gaping idlers in the street to endeavour to draw nearer to the mysterious portals. Thereupon three policemen on duty outside hustled the mob back, and Brett took advantage of the confusion thus created to slip to the doorway almost unperceived. One of the police constables turned round to make a grab at him, but a signal from a _confrere_ inside prevented this, and Brett quickly found himself within a s.p.a.cious entrance hall with the door closed and bolted behind him.
Winter was talking to two uniformed inspectors, to whom he had explained the barrister"s mission and credentials.
"We have here, Mr. Brett," he said, "Inspector Walters, who was on duty until ten o"clock on Monday night, and Inspector Sharpe, who relieved him. They will both tell you exactly what took place."
"Thank you," said the barrister, "but it will expedite matters if you gentlemen will first accompany me over the scene of the crime. I will then be able to understand more accurately what happened. Suppose we start here. I presume that this is where the police guard was stationed?"
Inspector Walters a.s.sumed the _role_ of guide.
"I was in charge of the first guard established a month ago," he said, "and the arrangements I then made have been adhered to without deviation night and day ever since."
From the outer door a short pa.s.sage of a few feet led up half a dozen steps into a large reception room, the entrance to which was closed by a light double door, half gla.s.s. On both sides of the first short pa.s.sage were two small apartments, such as are often used in London mansions for the purposes of cloak-rooms. The doors from these rooms opened into the inner hall. A large dining-room was situated on the left or Park side, and on the right was a breakfast or morning-room. At the back of the reception hall a handsome staircase led from left to right to the upper floors, whilst a doorway beneath the staircase gave access to the kitchens and bas.e.m.e.nt offices.
"Here," said the inspector, pointing to the foot of the staircase, "two police-constables were constantly stationed. Another stood there,"
indicating the pa.s.sage to the kitchen, "and a fourth at the gla.s.s door.
As the outer bas.e.m.e.nt entrance was not only securely fastened by bolts and bars, but actually bricked up inside, it was absolutely impossible for any person to enter or leave the house save by the front door, nor could any one go from the kitchen to the upper part of the house without pa.s.sing under the observation of all four constables. I arranged my guards in military fashion, having three men for each post, with one hour on duty and two hours off, but the same men were never on guard together at definite hours, as they were relieved at varying times. You will understand that I considered it a very responsible task to safeguard these premises, and thought it best to render it impossible for any section of the force under my command to take part in a conspiracy, although such a thing was in itself most improbable."
They then ascended the staircase and found themselves on the first floor.
There were six s.p.a.cious apartments on this storey, and all of them had originally opened on to the landing. The special precautions taken to guard the diamonds of the Turkish mission had altered all that. Five doorways had been bricked up, the result being that admission to the whole set of rooms could only be obtained through the first door that faced the top of the staircase.
This apartment was luxuriously furnished, and Inspector Walters explained that the Turkish Envoy and his suite pa.s.sed the working hours of each day there after they had personally thrown open the other apartments to the diamond polishers and unlocked the safes in which the gems were stored, when work ceased on the previous day.
"His Excellency," said the inspector, "kept the keys of this room and the others, together with those of the safes, in his own possession night and day. He slept upstairs, and so did the other two gentlemen. No one was allowed to come to this floor except the confidential servant, named Hussein, who used to bring coffee, cigars, and newspapers or other things the gentlemen might require, together with their lunch in the middle of the day. The workmen brought their lunch with them, so that they came in and out once a day only."
"Where did this confidential servant sleep?" said Brett.
"I believe he used to lie curled up on the rug outside his Excellency"s door."
"And the other servants?"
"They all slept in the bas.e.m.e.nt."
"What were they, Turks or Christians?"
"Well, sir," said the inspector with a smile, "two of them were Turks in costume, whilst three were Christians in appearance. That is the best I can say for the Christians, as they were Frenchmen, though certainly the cook was a first-rate _chef_. Of course, we all got our meals here whilst on duty."
"Did his Excellency and the other members of the mission eat food prepared in the ordinary way?"
"Oh, yes; they appreciated French dishes as keenly as anybody might do."
"It was in this room, then," continued Brett, "that the murders took place?"
"Yes; I suppose that must be so," said the inspector. "But my friend here," pointing to Inspector Sharpe, "can tell that part of the story better than I can."
They pa.s.sed into the inner rooms, which were quite silent and deserted, and presented a strange appearance considering the character of the house and its locality. Although the ceilings were decorated with beautiful paintings and fringed with superbly emblazoned mouldings, although the walls were papered with material that cost as much per yard as good silk, each apartment was occupied with workmen"s benches, and curious devices for cutting and polishing diamonds.
In the first room were two small safes, one of which was intended to receive the gems under treatment at the close of each day"s work; the other held certain valuable materials required in the diamond cutter"s operations. Three of the rooms were on the Park side, and it was here that the small colony of skilled artisans had been installed.
The other two rooms were not tenanted, nor had any communicating doors been broken through the walls in order to gain access to them.
The windows of the three apartments occupied by the workmen were not only guarded by strong iron bars, but possessed the additional security of external wire blinds of exceedingly small mesh. Each window admitted plenty of light, and could be raised to allow a free circulation of air, but it was seemingly quite impossible for any active communication to take place with the outside. The three rooms looked out over a small enclosed lawn, which was separated from the park by a brick wall surmounted by iron railings. All the fireplaces had been closed with bricks and mortar.
"You will see, sir," said the inspector, when he had called Brett"s attention to these details, "that mysterious though the murders were, they were as nothing compared with the disappearance of the diamonds.
Every person who came downstairs was most carefully and methodically searched each time he pa.s.sed the constable on duty at the bottom. It may be admitted that a few small stones could be so secreted as to escape observation, but some of these stones were so large that such a notion is not to be thought of, whilst the size of the great diamond which Mr.
Talbot christened the "Hen"s Egg" rendered its transference past the searchers beneath absolutely impossible. There was no humbug about the search, you will understand, Mr. Brett. People had to take their boots off, open their mouths, and hand over their hats, coats, sticks, or umbrellas for inspection. Every part of their clothing was scrutinised, and the contents of their pockets, money, watches, keys, and the rest, thoroughly examined. These were our orders, and they were strictly obeyed, Mr. Talbot himself being the first to insist that the regulation should be carried out rigidly, so far as he was concerned. Why, one day a Cabinet Minister came here to see the diamonds. He was elderly and stout, and did not at all like having to take off his boots, I can a.s.sure you, as he nearly got apoplexy whilst lacing them up again."
During the inspector"s running comments Brett had carefully scrutinised each of the windows. He at once came to the conclusion, by a simple a.n.a.lysis of the possibilities, that by no other means than through the barrier of iron wire had the diamonds pa.s.sed out of the house; but the most thorough examination failed to reveal any loophole by which this achievement had been accomplished. He opened each of the windows, tested every iron bar, and saw that the fastenings of the external blind were undisturbed, whilst the fine wire mesh showed no irregularities in its hexagonal pattern wherein any defect would at once be visible.
"We have done all that long since, sir," said the second police officer, smiling at the obviousness of an amateur"s method of inspection, for it happened that he had never met the barrister before, though he had often heard of him.
