on an empty stomach." Thorndyke and I had meanwhile clothed ourselves with a celerity known only to medical practitioners and quick-change artists, and in a few minutes descended the stairs together, calling in at the laboratory for a few appliances that Thorndyke usually took with him on a visit of investigation.
As we entered the sitting-room, our visitor, who was feverishly pacing up and down, seized his hat with a gasp of relief. "You are ready to come?" he asked. "My carriage is at the door;" and, without waiting for an answer, he hurried out, and rapidly preceded us down the stairs.
The carriage was a roomy brougham, which fortunately accommodated the three of us, and as soon as we had entered and shut the door, the coachman whipped up his horse and drove off at a smart trot.
"I had better give you some account of the circumstances, as we go," said our agitated friend. "In the first place, my name is Curtis, Henry Curtis; here is my card. Ah! and here is another card, which I should have given you before. My solicitor, Mr. Marchmont, was with me when I made this dreadful discovery, and he sent me to you. He remained in the rooms to see that nothing is disturbed until you arrive."
"That was wise of him," said Thorndyke. "But now tell us exactly what has occurred."
"I will," said Mr. Curtis. "The murdered man was my brother-in-law, Alfred Hartridge, and I am sorry to say he was—well, he was a bad man. It grieves me to speak of him thus—de mortuis, you know—but, still, we must deal with the facts, even though they be painful."
"Undoubtedly," agreed Thorndyke.
"I have had a great deal of very unpleasant correspondence with him—Marchmont will tell you about that—and yesterday I left a note for him, asking for an interview, to settle the business, naming eight o'clock this morning as the hour, because I had to leave town before noon. He replied, in a very singular letter, that he would see me at that hour, and Mr. Marchmont very kindly consented to accompany me. Accordingly, we went to his chambers together this morning, arriving punctually at eight o'clock. We rang the bell several times, and knocked loudly at the door, but as there was no response, we went down and spoke to the hall-porter. This man, it seems, had already noticed, from the courtyard, that the electric lights were full on in Mr. Hartridge's sitting-room, as they had been all night, according to the statement of the night-porter; so now, suspecting that something was wrong, he came up with us, and rang the bell and battered at the door. Then, as there was still no sign of life within, he inserted his duplicate key and tried to open the door—unsuccessfully, however, as it proved to be bolted on the inside. Thereupon the porter fetched a constable, and, after a consultation, we decided that we were justified in breaking open the door; the porter produced a crowbar, and by our unified efforts the door was eventually burst open. We entered, and—my God! Dr. Thorndyke, what a terrible sight it was that met our eyes! My brother-in-law was lying dead on the floor of the sitting-room. He had been stabbed—stabbed to death; and the dagger had not even been withdrawn. It was still sticking out of his back."
He mopped his face with his handkerchief, and was about to continue his account of the catastrophe when the carriage entered a quiet side-street between Westminster and Victoria, and drew up before a block of tall, new, red-brick buildings. A flurried hall-porter ran out to open the door, and we alighted opposite the main entrance.
"My brother-in-law's chambers are on the second-floor," said Mr. Curtis. "We can go up in the lift."
The porter had hurried before us, and already stood with his hand upon the rope. We entered the lift, and in a few seconds were discharged on to the second floor, the porter, with furtive curiosity, following us down the corridor. At the end of the passage was a half-open door, considerably battered and bruised. Above the door, painted in white lettering, was the inscription, "Mr. Hartridge"; and through the doorway protruded the rather foxy countenance of Inspector Badger.
"I am glad you have come, sir," said he, as he recognized my colleague. "Mr. Marchmont is sitting inside like a watch-dog, and he growls if any of us even walks across the room."
The words formed a complaint, but there was a certain geniality in the speaker's manner which made me suspect that Inspector Badger was already navigating his craft on a lee shore.
We entered a small lobby or hall, and from thence passed into the sitting-room, where we found Mr. Marchmont keeping his vigil, in company with a constable and a uniformed inspector. The three rose softly as we entered, and greeted us in a whisper; and then, with one accord, we all looked towards the other end of the room, and so remained for a time without speaking.
There was, in the entire aspect of the room, something very grim and dreadful. An atmosphere of tragic mystery enveloped the most commonplace objects; and sinister suggestions lurked in the most familiar appearances. Especially impressive was the air of suspense—of ordinary, every-day life suddenly arrested—cut short in the twinkling of an eye. The electric lamps, still burning dim and red, though the summer sunshine streamed in through the windows; the half-emptied tumbler and open book by the empty chair, had each its whispered message of swift and sudden disaster, as had the hushed voices and stealthy movements of the waiting men, and, above all, an awesome shape that was but a few hours since a living man, and that now sprawled, prone and motionless, on the floor.
"This is a mysterious affair," observed Inspector Badger, breaking the silence at length, "though it is clear enough up to a certain point. The body tells its own story."
We stepped across and looked down at the corpse. It was that of a somewhat elderly man, and lay, on an open space of floor before the fireplace, face downwards, with the arms extended. The slender hilt of a dagger projected from the back below the left shoulder, and, with the exception of a trace of blood upon the lips, this was the only indication of the mode of death. A little way from the body a clock-key lay on the carpet, and, glancing up at the clock on the mantelpiece, I perceived that the glass front was open.
"You see," pursued the inspector, noting my glance, "he was standing in front of the fireplace, winding the clock. Then the murderer stole up behind him—the noise of the turning key must have covered his movements—and stabbed him. And you see, from the position of the dagger on the left side of the back, that the murderer must have been left-handed. That is all clear enough. What is not clear is how he got in, and how he got out again."
"The body has not been moved, I suppose," said Thorndyke.
"No. We sent for Dr. Egerton, the police-surgeon, and he certified that the man was dead. He will be back presently to see you and arrange about the post-mortem."
"Then," said Thorndyke, "we will not disturb the body till he comes, except to take the temperature and dust the dagger-hilt."
He took from his bag a long, registering chemical thermometer and an insufflator or powder-blower. The former he introduced under the dead man's clothing against the abdomen, and with the latter blew a stream of fine yellow powder on to the black leather handle of the dagger. Inspector Badger stooped eagerly to examine the handle, as Thorndyke blew away the powder that had settled evenly on the surface.
"No finger-prints," said he, in a disappointed tone. "He must have worn gloves. But that inscription gives a pretty broad hint."
He pointed, as he spoke, to the metal guard of the dagger, on which was engraved, in clumsy lettering, the single word, "TRADITORE."
"That's the Italian for 'traitor,'" continued the inspector, "and I got some information from the porter that fits in with that suggestion. We'll have him in presently, and you shall hear."
"Meanwhile," said Thorndyke, "as the position of the body may be of importance in the inquiry, I will take one or two photographs and make a rough plan to scale. Nothing has been moved, you say? Who opened the windows?"
"They were open when we came in," said Mr. Marchmont. "Last night was very hot, you remember. Nothing whatever has been moved."
Thorndyke produced from his bag a small folding camera, a telescopic tripod, a surveyor's measuring-tape, a boxwood scale, and a sketch-block. He set up the camera in a corner, and exposed a plate, taking a general view of the room, and including the corpse. Then he moved to the door and made a second exposure.
