"Yes, sir. There was two cases, a square one and a long, narrow one, about five foot long. I helped him to carry them down to the cab."
"Which was a four-wheeler, I suppose?"
"Yes, sir."
"Mr. Barlow hasn't been here very long, has he?" Thorndyke inquired.
"No. He only came in last quarter-day—about six weeks ago."
"Ah well! I must call another day. Good-morning;" and Thorndyke strode out of the building, and made directly for the cab-rank in the adjoining street. Here he stopped for a minute or two to parley with the driver of a four-wheeled cab, whom he finally commissioned to convey us to a shop in New Oxford Street. Having dismissed the cabman with his blessing and a half-sovereign, he vanished into the shop, leaving me to gaze at the lathes, drills, and bars of metal displayed in the window. Presently he emerged with a small parcel, and explained, in answer to my inquiring look: "A strip of tool steel and a block of metal for Polton."
His next purchase was rather more eccentric. We were proceeding along Holborn when his attention was suddenly arrested by the window of a furniture shop, in which was displayed a collection of obsolete French small-arms—relics of the tragedy of 1870—which were being sold for decorative purposes. After a brief inspection, he entered the shop, and shortly reappeared carrying a long sword-bayonet and an old Chassepôt rifle.
"What may be the meaning of this martial display?" I asked, as we turned down Fetter Lane.
"House protection," he replied promptly. "You will agree that a discharge of musketry, followed by a bayonet charge, would disconcert the boldest of burglars."
I laughed at the absurd picture thus drawn of the strenuous house-protector, but nevertheless continued to speculate on the meaning of my friend's eccentric proceedings, which I felt sure were in some way related to the murder in Brackenhurst Chambers, though I could not trace the connection.
After a late lunch, I hurried out to transact such of my business as had been interrupted by the stirring events of the morning, leaving Thorndyke busy with a drawing-board, squares, scale, and compasses, making accurate, scaled drawings from his rough sketches; while Polton, with the brown-paper parcel in his hand, looked on at him with an air of anxious expectation.
As I was returning homeward in the evening by way of Mitre Court, I overtook Mr. Marchmont, who was also bound for our chambers, and we walked on together.
"I had a note from Thorndyke," he explained, "asking for a specimen of handwriting, so I thought I would bring it along myself, and hear if he has any news."
When we entered the chambers, we found Thorndyke in earnest consultation with Polton, and on the table before them I observed, to my great surprise, the dagger with which the murder had been committed.
"I have got you the specimen that you asked for," said Marchmont. "I didn't think I should be able to, but, by a lucky chance, Curtis kept the only letter he ever received from the party in question."
He drew the letter from his wallet, and handed it to Thorndyke, who looked at it attentively and with evident satisfaction.
"By the way," said Marchmont, taking up the dagger, "I thought the inspector took this away with him."
"He took the original," replied Thorndyke. "This is a duplicate, which Polton has made, for experimental purposes, from my drawings."
"Really!" exclaimed Marchmont, with a glance of respectful admiration at Polton; "it is a perfect replica—and you have made it so quickly, too."
"It was quite easy to make," said Polton, "to a man accustomed to work in metal."
"Which," added Thorndyke, "is a fact of some evidential value."
At this moment a hansom drew up outside. A moment later flying footsteps were heard on the stairs. There was a furious battering at the door, and, as Polton threw it open, Mr. Curtis burst wildly into the room.
"Here is a frightful thing, Marchmont!" he gasped. "Edith—my daughter—arrested for the murder. Inspector Badger came to our house and took her. My God! I shall go mad!"
Thorndyke laid his hand on the excited man's shoulder. "Don't distress yourself, Mr. Curtis," said he. "There is no occasion, I assure you. I suppose," he added, "your daughter is left-handed?"
"Yes, she is, by a most disastrous coincidence. But what are we to do? Good God! Dr. Thorndyke, they have taken her to prison—to prison—think of it! My poor Edith!"
"We'll soon have her out," said Thorndyke. "But listen; there is someone at the door."
A brisk rat-tat confirmed his statement; and when I rose to open the door, I found myself confronted by Inspector Badger. There was a moment of extreme awkwardness, and then both the detective and Mr. Curtis proposed to retire in favour of the other.
"Don't go, inspector," said Thorndyke; "I want to have a word with you. Perhaps Mr. Curtis would look in again, say, in an hour. Will you? We shall have news for you by then, I hope."
Mr. Curtis agreed hastily, and dashed out of the room with his characteristic impetuosity. When he had gone, Thorndyke turned to the detective, and remarked dryly:
"You seem to have been busy, inspector?"
"Yes," replied Badger; "I haven't let the grass grow under my feet; and I've got a pretty strong case against Miss Curtis already. You see, she was the last person seen in the company of the deceased; she had a grievance against him; she is left-handed, and you remember that the murder was committed by a left-handed person."
"Anything else?"
"Yes. I have seen those Italians, and the whole thing was a put-up job. A woman, in a widow's dress and veil, paid them to go and play the fool outside the building, and she gave them the letter that was left with the porter. They haven't identified her yet, but she seems to agree in size with Miss Curtis."
"And how did she get out of the chambers, with the door bolted on the inside?"
"Ah, there you are! That's a mystery at present—unless you can give us an explanation." The inspector made this qualification with a faint grin, and added: "As there was no one in the place when we broke into it, the murderer must have got out somehow. You can't deny that."
"I do deny it, nevertheless," said Thorndyke. "You look surprised," he continued (which was undoubtedly true), "but yet the whole thing is exceedingly obvious. The explanation struck me directly I looked at the body. There was evidently no practicable exit from the flat, and there was certainly no one in it when you entered. Clearly, then, the murderer had never been in the place at all."
"I don't follow you in the least," said the inspector.
"Well," said Thorndyke, "as I have finished with the case, and am handing it over to you, I will put the evidence before you seriatim. Now, I think we are agreed that, at the moment when the blow was struck, the deceased was standing before the fireplace, winding the clock. The dagger entered obliquely from the left, and, if you recall its position, you will remember that its hilt pointed directly towards an open window."
"Which was forty feet from the ground."
"Yes. And now we will consider the very peculiar character of the weapon with which the crime was committed."
He had placed his hand upon the knob of a drawer, when we were interrupted by a knock at the door. I sprang up, and, opening it, admitted no less a person than the porter of Brackenhurst Chambers. The man looked somewhat surprised on recognizing our visitors, but advanced to Thorndyke, drawing a folded paper from his pocket.
"I've found the article you were looking for, sir," said he, "and a rare hunt I had for it. It had stuck in the leaves of one of them shrubs."
Thorndyke opened the packet, and, having glanced inside, laid it on the table.
"Thank
