So I entered Sperry’s library with appreciation. He was standing by the fire, with the grave face and slightly bent head of his professional manner. We say, in the neighborhood, that Sperry uses his professional manner as armor, so I was rather prepared to do battle; but he forestalled me.

“Horace,” he said, “I have been a fool, a driveling idiot. We were getting something at those sittings. Something real. She’s wonderful. She’s going to give it up, but the fact remains that she has some power we haven’t, and now I’ve discredited her! I see it plainly enough.” He was rather bitter about it, but not hostile. His fury was at himself. “Of course,” he went on, “I am sure that she got nothing from Hawkins. But the fact remains—” He was hurt in his pride of her.

“I wonder,” I said, “if you kept the letter Hawkins wrote you when he asked for a position.”

He was not sure. He went into his consulting room and was gone for some time. I took the opportunity to glance over his books and over the room.

Arthur Wells’s stick was standing in a corner, and I took it up and examined it. It was an English malacca, light and strong, and had seen service. It was long, too long for me; it occurred to me that Wells had been about my height, and that it was odd that he should have carried so long a stick. There was no ease in swinging it.

From that to the memory of Hawkins’s face when Sperry took it, the night of the murder, in the hall of the Wells house, was only a step. I seemed that day to be thinking considerably about Hawkins.

When Sperry returned I laid the stick on the table. There can be no doubt that I did so, for I had to move a book-rack to place it. One end, the handle, was near the ink-well, and the ferrule lay on a copy of Gibson’s “Life Beyond the Grave,” which Sperry had evidently been reading.

Sperry had found the letter. As I glanced at it I recognized the writing at once, thin and rather sexless, Spencerian.

Dear Sir: Since Mr. Wells’s death I am out of employment. Before I took the position of butler with Mr. Wells I was valet to Mr. Ellingham, and before that, in England, to Lord Condray. I have a very good letter of recommendation from Lord Condray. If you need a servant at this time I would do my best to give satisfaction.
