“Certainly. I quite see the grim humour of the situation,” I said.

“And if you had not assisted me, Mr Kemball, I should, at this moment, have been under detention in His Majesty’s prison at Brixton,” he said. “By the way, I have to return the suit of clothes you so very kindly lent to me. My man has them upstairs ready packed. I shall send them to you by parcel-post. Gates was, I think, rather surprised to find another man’s clothes among my kit. But fortunately he’s used to my idiosyncrasies, and regards them as mere eccentricities on the part of his master. But he is always discreet. He’s been with me these ten years.”

“How long have you lived here, Mr—er—”

“Shaw here,” he interrupted quickly.

“Mr Shaw. How long have you lived here? I thought the place belonged to Lord Wyville?”

“So it does—at least to the late lord’s executors. I’ve rented it for the past three years. So in the county I’m highly respectable, and I believe highly respected.”

“The situation is unusual—to say the least,” I declared.

“Perhaps I’m a rather unusual man, Mr Kemball,” he said, rising and crossing the room. I saw that in his dark green cravat he wore a fine diamond, and that his manner and bearing were those of a well-born country gentleman. Truly, he was an unusual person.

“I hope,” he went on, halting suddenly before me, “that as you have associated yourself with my very dear and intimate friend, Melvill Arnold, you will now become my friend also. It is for that reason I venture to approach you as I have done to-day.”

“Well,” I said, my natural sense of caution exerting itself as I recollected the dead man’s written injunction, “I must admit, Mr Shaw, that I am sorely puzzled to fathom the mystery of the situation. Ever since my meeting with poor Mr Arnold I seem to have been living in a perfect maze of inexplicable circumstances.”
