of anything that would explain this attack on you?"
"No."
"Then the next question is: Had you any property of value on your person?"
"No. Five pounds would cover the value of everything I had about me, including the instruments."
"Then that seems to exclude robbery as a motive. The next question is: Does any person stand to benefit considerably by your death? Have you any considerable expectations in the way of bequests, reversions or succession to landed property or titles?"
"No," I replied with a faint grin. "I shall come in for a thousand or two when my uncle dies, but I believe the London Hospital is the alternative legatee, and I suppose we would hardly suspect the hospital governors of this little affair. Otherwise, the only person who would benefit by my death would be the undertaker who got the contract to plant me."
Thorndyke nodded and made a note of my answer. "That," said he "disposes of the principal motives for premeditated murder. There remains the question of personal enmity—not a common motive in this country. Have you, as far as you know, an enemy or enemies who might conceivably try to kill you?"
"As far as I know, I have not an enemy in the world, or anyone, even, who would wish to do me a bad turn."
"Then," said Thorndyke, " that seems to dispose of all the ordinary motives for murder; and I may say that I have only put these questions as a matter of routine precaution—ex abundantia cautelae, as Jervis says, when he is in a forensic mood—because certain other facts which I have learned seem to exclude any of these motives except, perhaps, robbery from the person."
"You haven't been long picking up those other facts," remarked Jervis. "Why the affair only happened last night."
"I have only made a few simple enquiries," replied Thorndyke. "This morning I called on Mr. Highfield, whose name, as solicitor and agent to the landlords, I copied from the notice on the gate at the works last night. He knows me slightly so I was able to get from him the information that I wanted. It amounts to this.
"About four months ago, a Mr. Gill wrote to him and offered a lump sum for the use of the mineral water works for six months. Highfield accepted the offer and drew up an agreement, as desired, granting Gill immediate possession of the premises and the small stock and plant, of which the residue was to be taken back at a valuation by the landlords at the expiration of the term.
"I noted Gill's address, as it appeared on the agreement, and sent my man, Polton, to make enquiries.
"The address is that of a West Kensington lodging house at which Gill was staying when he signed the agreement. He had been there only three weeks, he left two days after the date of the agreement and the landlady does not know where he went or anything about him."
"Sounds a bit fishy," Jervis remarked. "Did he tell Highfield what he wanted the premises for?"
"I understood that something was said about some assay work in connection with certain—or rather uncertain—mineral concessions. But of course that was no affair of Highfield's. His business was to get the rent, and, having got it, his interest in Mr. Gill lapsed. But you see the bearing of these facts. Gill's connection with these works does, as Jervis says, look a little queer, especially after what has happened. But, seeing that he made his arrangements four months ago, at a time when Jardine had no thought of coming into this neighbourhood, it is clear that those arrangements could have no connection with this particular attempt. Gill obviously did not take those works with the intention of murdering Jardine. He took them for some other purpose; quite possibly the purpose that he stated. And we must not assume that Gill was the perpetrator of this outrage at all. Could you identify the man who let you in?"
"No," I replied. "Certainly not. I hardly saw him at all. The place was pitch dark, and whenever he struck a match he was either behind me or in front with his back to me. The only thing I could make out about him was that he had some sort of coarse wash-leather gloves on."
"Ha!" exclaimed Thorndyke. "Then we were right, Jervis."
I looked in surprise from one to the other of my friends, and was on the point of asking Thorndyke what he meant, when he continued. "That closes another track. If you couldn't identify the man, a description of Gill, if we could obtain it, would not help us. We must begin at some other point."
"It seems to me," said Jervis, "that we haven't much to go upon at all."
"We haven't much," agreed Thorndyke, "but still we have something. We find that the motive of this attempt was apparently not robbery, nor the diversion of inheritable property, nor personal enmity. It must have been premeditated, but yet it could not have been planned more than a week in advance, for Jardine has only been in this neighbourhood for that time, and his coming was unexpected. The appearances very strongly suggest that the motive, whatever it was, has been generated recently and probably locally. So we had better make a start from that assumption."
"Is it possible," Jervis suggested, "that this man Gill may be some sort of anarchist crank? Or a sort of thug? It is actually conceivable that he may have taken these premises for the express purpose of having a secure place where he could perpetrate murders and conceal the bodies."
"It is quite conceivable," said Thorndyke, "and when we go and look over the works—which I propose we do presently—we may as well bear the possibility in mind. But it is merely a speculative suggestion. To return to your affairs, Jardine, has your stay here been quite uneventful?"
"Perfectly," I replied.
"No unusual or obscure cases? No injuries?"
"No, nothing out of the common," I replied.
"No deaths?"
"One. But the man died before I took over."
"Nothing unusual about that? Everything quite regular?"
"Oh, perfectly," I answered; and then with a sudden qualm, as I recalled Batson's uncertainty as to the actual cause of death, I added, "At least I hope so."
"You hope so?" queried Thorndyke. "Yes. Because it's too late to go into the question now. The man was cremated."
At this a singular silence fell. Both my friends seemed to stiffen in their chairs, and both looked at me silently but very attentively. Then Thorndyke asked, "Did you have anything to do with that case?"
"Yes," I replied. "I went with Batson to examine the body."
"And are you perfectly satisfied that everything was as it should be?"
I was on the point of saying "yes." And then suddenly there arose before my eyes the vision of Mrs. Samway looking at me over Batson's shoulder with that strange, inscrutable expression. And again, I recalled her unexplained anger and then her sudden change of mood. It had impressed me uncomfortably at the time, and it impressed me uncomfortably now. "I don't know that I am, now that I come to think it over," I replied.
"Why not?" asked Thorndyke. "Well," I said, a little hesitatingly, "to begin with, I don't think the cause of death was quite clear, Batson couldn't find anything definite when he attended the man, and I know that the patient's death came as quite a surprise."
"But surely," exclaimed Thorndyke, "he took some measures to find out the cause of death!"
"He didn't. He assumed that it was a case of fatty heart and certified it as 'Morbus
