“I've tried my level best, but so far—nothing doing.”

He got up and stood before the mantel, his back against it, his hands in his pockets.

“I've found out one thing,” he said. “He's used to houses like this. Every now and again he lets something out quite natural. He knew that the furniture in his room was Jacobean—that's what he called it—and he knew it was fine stuff. He wouldn't have known that if he'd been a piker. I'm going to try if he won't let out something else when he sees things here—if he'll come.”

“You have such a wonderfully reasoning mind, dear,” said Miss Alicia, as she rose. “You would have made a great detective, I'm sure.”

“If Ann had been with him,” he said, rather gloomily, “she'd have caught on to a lot more than I have. I don't feel very chesty about the way I've managed it.”

Miss Alicia went up-stairs shortly afterward, and half an hour later Tembarom told the footmen in the hall that they might go to bed. The experiment he was going to make demanded that the place should be cleared of any disturbing presence. He had been thinking it over for sometime past. He had sat in the private room of the great nerve specialist in London and had talked it over with him. He had talked of it with the duke on the lawn at Stone Hover. There had been a flush of color in the older man's cheek-bones, and his eyes had been alight as he took his part in the discussion. He had added the touch of his own personality to it, as always happened.

“We are having some fine moments, my good fellow,” he had said, rubbing his hands. “This is extremely like the fourth act. I'd like to be sure what comes next.”

“I'd like to be sure myself,” Tembarom answered. “It's as if a flash of lightning came sometimes, and then things clouded up. And sometimes when I am trying something out he'll get so excited that I daren't go on until I've talked to the doctor.”

It was the excitement he was dubious about to-night. It was not possible to be quite certain as to the entire safety of the plan; but there might be a chance—even a big chance—of wakening some cell from its deadened sleep. Sir Ormsby way had talked to him a good deal about brain cells, and he had listened faithfully and learned more than he could put into scientific English. Gradually, during the past months, he had been coming upon strangely exciting hints of curious possibilities. They had been mere hints at first, and had seemed almost absurd in their unbelievableness. But each one had linked itself with another, and led him on to further wondering and exploration. When Miss Alicia and Palliser had seen that he looked absorbed and baffled, it had been because he had frequently found himself, to use his own figures of speech, “mixed up to beat the band.” He had not known which way to turn; but he had gone on turning because he could not escape from his own excited interest, and the inevitable emotion roused by being caught in the whirl of a melodrama. That was what he'd dropped into—a whacking big play. It had begun for him when Palford butted in that night and told him he was a lost heir, with a fortune and an estate in England; and the curtain had been jerking up and down ever since. But there had been thrills in it, queer as it was. Something doing all the time, by gee!

He sat and smoked his pipe and wished Ann were with him because he knew he was not as cool as he had meant to be. He felt a certain tingling of excitement in his body; and this was not the time to be excited. He waited for some minutes before he went up-stairs. It was true that Strangeways had been much better lately. He had seemed to find it easier to follow conversation. During the past few days, Tembarom had talked to him in a matter-of-fact way about the house and its various belongings. He had at last seemed to waken to an interest in the picture-gallery. Evidently he knew something of picture-galleries and portraits, and found himself relieved by his own clearness of thought when he talked of them.
