said Brett, "but you admit, no doubt, that this is a very remarkable crime I am investigating."
"I should just think it is, sir," was the answer.
"Well, now, does it not strike you that the perpetrators thereof, who were not afraid to be scrutinized by yourself and by several other policemen, and to be searched and further scrutinized by a different set of officers when they came out again, would be very unlikely persons to bear about them such distinguishing characteristics as would lead to their arrest by the first youthful police-constable who encountered them? I do not want to be rude, or to indicate any lack of discretion on your part, but, from my point of view, I would vastly prefer not to be furnished with any description of these three persons, nor would I care to have seen them as they entered or left the house."
"Well, that is very curious," said Inspector Walters, dropping his hands on his knees in sheer amazement at such an extraordinary statement from a man whose clearness and accuracy of perception had been so fully justified by the incident of the window-blind.
"And now, Mr. Sharpe," said Brett, turning to the other officer, "what did you observe?"
"I came on duty at ten o'clock, sir; posted my guards, and received from Inspector Walters an exact account of what had taken place before my arrival. Inspector Walters had hardly quitted the house, when one of the junior members of the mission came downstairs with a note which he asked me to send at once by a constable to Mr. Talbot."
"You are quite sure he was one of the members of the mission?" said Brett.
"Perfectly certain. I have seen him every previous night for nearly a month, as the gentleman often went out late to the Turkish Embassy, and elsewhere. I sent the note, as requested, and Mr. Talbot came back with the constable in about twenty minutes. Mr. Talbot went upstairs accompanied by Hussein; Hussein came down, was searched, went down to the kitchen, brought up more coffee, and never appeared again. The next time I saw him was about noon yesterday, when we broke open the door, and found his dead body. At 11.25, Mr. Talbot, accompanied by the one whom Inspector Walters has described as the spokesman of the strangers, came down the stairs. Mr. Talbot looked somewhat puzzled, but not specially worried, and submitted himself to the searching operation as usual. The other man seemed to be surprised by this proceeding, but offered no objection when his turn came, and said something laughingly in French to Mr. Talbot, when he had to take his boots off. The two gentlemen went outside and called a cab. Mr. Talbot got in, and the constable at the door heard the foreigner tell the driver to go to the Carlton Hotel. He repeated the address twice, so as to make sure the man would make no mistake.
"Then they drove off, and there was no further incident to report until five minutes past twelve, when the other two foreigners came downstairs. Then we had a bit of a job. They knew no English, and one of our men, who could speak French, found that they did not understand that language. However, at last in dumb show we got them to perceive that everybody who came downstairs had to be searched. They submitted at once, and I took special care that the investigation was complete. There was nothing upon them to arouse the slightest suspicion, no weapons of any sort beyond a small pocket-knife carried by one man, and not much in the way of either papers or money. Before going out one of them produced a small card on which was written, 'Carlton Hotel.'
"I took it that this was their residence, so I instructed a constable to see them into a cab and tell the driver where to take them. I also showed them how much money to give the cabman. None of the gentlemen upstairs put in an appearance, nor did I hear them retire to rest. To make quite sure that all was right, I and a sergeant who looked in a little later, went upstairs and tried the door of the ante-room. This was locked and everything was quiet within, so we returned to the hall, and the night was passed in the usual manner. Hussein always made his appearance about eight o'clock in the morning, when he came down to procure coffee for his Excellency and the others. As he did not show up I wondered what had become of him. When nine o'clock came, I determined to investigate matters. By that time the diamond cutters had put in an appearance, and were gathered in the hall, undergoing a slight search preparatory to their day's work."
"How many of these men were there?" broke in Brett.
"Fourteen exactly. They were mostly Dutchmen, with, I think three Belgians. Taking a constable with me, I went upstairs, and ascended to the second storey, where I knew his Excellency's suite was situated, and where I expected to find Hussein asleep on a mat in front of the bedroom door. The mat was there, but no Hussein. Then I went higher up to the rooms occupied by the two assistants. I knocked, but received no answer. One door was locked; the other was open, so I went in, but the room was empty, and the bed had not been slept upon. This seemed so strange that I knocked loudly at the other door, with no result. I returned to his Excellency's floor and hammered at the door, which was locked, sufficiently to wake the soundest sleeper that ever lived. This again was useless, so I returned downstairs and sent off two messengers post haste—one to Mr. Talbot, and the other to the Commissioner of Police at Scotland Yard. The man who went to Mr. Talbot's house returned first, bringing the startling information that Mr. Talbot had not been home all night, and that his uncle and sister were anxious to know where he was, as they had received no message from him since he quitted the house the previous night at 10.15. The Commissioner of Police came himself a little later. By that time Inspector Walters had reached here for his turn of day duty, and after a hasty consultation we decided to break in all the doors that were locked, commencing with that of the second assistant. His room was empty, and so was his Excellency's, neither apartment having been occupied during the night. We then returned to the first floor and forced the door of the ante-room, which, we discovered, was only secured by a spring latch, the lower lock not having been used. As soon as we entered the room, we found the four dead men. Hussein, the servant, was nearest the door and was lying in a crumpled-up position. He had been stabbed twice through the back and once through the spinal column at the base of the neck. His Excellency and the two assistants were seated in chairs, but had been stabbed through the heart. The instrument used must have been a long thin dagger or stiletto. There was no sign of it anywhere in the room, and most certainly none of the men who came out the previous night had such a weapon concealed upon him.
"Doctors were at once sent for, and the first medical gentlemen to arrive said that each of the four had been dead for many hours, but they also imagined that the coffee, the remains of which we found in some cups on the table, had been drugged. So, before disturbing the room and its contents in any way, the Commissioner sent for Dr. Tennyson Coke. After careful investigation Dr. Coke came to the same conclusion as the other gentlemen. He believes that his Excellency and his two assistants were first stupefied by the drug and then murdered as they sat in their chairs, whilst the appearance of Hussein and the nature of his wounds seemed to indicate that he had been unexpectedly attacked and killed before he could struggle effectually or even call for assistance.
"Of course, the diamonds had vanished, whilst in the safes or on the tables we found the keys which had evidently been taken from his Excellency's pockets. We were all puzzled to account for the disappearance of the diamonds and the dagger, but you have clearly shown the means whereby they were conveyed off the premises. Dr. Coke took away the coffee for analysis. The four bodies were carried to the mortuary in Chapel Place, and the fourteen workmen were conveyed to Scotland Yard, not because we have any charge against them, but the Commissioner thought it best to keep them under surveillance until the Turkish Embassy had settled what was to be done with them, in the matter of paying such wages as were due and sending them back to Amsterdam. The men themselves, I may add, were quite satisfied with our action in the matter. That is really all I have to tell you."
"It is quite clear, then," said Brett, "that two men succeeded in murdering four and in getting away with their plunder and arms without creating the slightest noise or exciting any suspicion in your mind."
"That is so," admitted Inspector Sharpe ruefully.
"Then," said Brett, "there is nothing else to
