"The will, as I rather expected when I examined the recess last night, had slipped down a rather wide crack at the end of the stair timber, which, you know, formed, so to speak, the floor of the recess. The fact was, the stair-tread didn't quite reach as far as the back of the recess. The opening wasn't very distinct to see, but I soon felt it with my fingers. When Miss Garth, in her hypnotic condition on Saturday night, dropped the will into the recess, it shot straight to the back corner and fell down the slit. That was why Mellis found it empty, and why Miss Garth also found it empty on returning there last night under hypnotic influence. You observed her terrible state of nervous agitation when she failed to carry out the command that haunted her. It was frightful. Something like what happens to a suddenly awakened somnambulist, perhaps. Anyway, that is all over. I found the will under the end of the stair-tread, and here it is. If you will come to the small staircase now you shall see where the paper slipped out of sight. Perhaps we shall meet Mr. Mellis."
"He's a scoundrel," said Mr. Crellan. "It's a pity we can't punish him."
"That's impossible, of course. Where's your proof? And if you had any I'm not sure that a hypnotist is responsible at law for what his subject does. Even if he were, moving a will from one part of the house to another is scarcely a legal crime. The explanation I have given you accounts entirely for the disturbed manner of Miss Garth in the presence of Mellis. She merely felt an indefinite sense of his power over her. Indeed, there is all the possibility that, finding her an easy subject, he had already practised his influence by way of experiment. A hypnotist, as you will see in the books, has always an easier task with a person he has hypnotised before."
As Hewitt had guessed, in the corridor they met Mr. Mellis. He was a thin, dark man of about thirty-five, with large, bony features, and a slight stoop. Mr. Crellan glared at him ferociously.
"Well, sir, and what do you want?" he asked.
Mr. Mellis looked surprised. "Really, that's a very extraordinary remark, Mr. Crellan," he said. "This is my late uncle's house. I might, with at least as much reason, ask you what you want."
"I'm here, sir, as Mr. Holford's executor."
"Appointed by will?"
"Yes."
"And is the will in existence?"
