“Out of the clock?” said Tom. “We can soon see whether anybody’s hidden there.” Speaking thus, he withdrew his arm, and flung open the door of the clock. Enough light came from the lamp on the stairs to show that the old case was empty of everything, save the weights, chains, and pendulum of the clock.

“Wherever else the voice may have come from, it is plain that it couldn’t come from here,” said Tom, as he proceeded to relight the widow’s candle.

“It came from there, I’m quite certain. There were three distinct raps from the inside as well.”

“Thanks. I shall feel obliged by your doing so. You will say nothing of all this downstairs?”

“I should not think of doing so.”

The following day Mr. Bristow was not at luncheon. There were one or two inquiries, but no one seemed to know exactly what had become of him. It was Mrs. McDermott’s usual practice to retire to the library for an hour after luncheon—which room she generally had all to herself at such times—for the ostensible purpose of reading the newspapers, but, it may be, quite as much for the sake of a quiet sleep in the huge leathern chair that stood by the library fire. On going there as usual after luncheon to-day, what was the widow’s surprise to find Mr. Bristow sitting there fast asleep, with the “Times” at his feet where it had dropped from his relaxed fingers.

She stepped up to him on tiptoe and looked closely at him. “Rather nice-looking,” she said to herself. “Shall I disturb him, or not?”
