Sir Thomas listened with a sinking heart. "Play," he thought to himself. "Play, play, play, already! It was his father's curse, poor fellow, and I hope it won't be Harry's. It's some comfort to think, anyhow, that it's only billiards."

"Well, good night, Tom," Harry went on, ringing the bell as he spoke.

"Good night, Harry. I hope next time the cards won't go so persistently against you."

The cards! Phew! That was bad indeed. Sir Thomas started. He didn't object to a quiet after-dinner rubber on his own account, naturally: but this wasn't whist; oh, no; nothing of the sort. This was evidently serious playing. He drew a long breath, and felt he must talk very decidedly about the matter to Harry to-morrow morning.

"Is my uncle home yet, Wilkins?"

"No, sir; he said he wouldn't be back probably till two o'clock, and we wasn't to sit up for him."

"All right then. Give me a light for a minute in the library. I'll take a seltzer before I go upstairs, just to steady me."

Sir Thomas almost laughed outright. This was really too ridiculous. Suppose, after all the waiting, Harry was to come over and discover him sitting there in the darkness by the window, what a pretty figure he would cut before him. And besides, the whole thing would have to come out then, and after all the thief would never be discovered and punished. The Colonel grew hot and red in the face, and began to wish to goodness he hadn't in the first place let himself in, in any way, for this ridiculous amateur detective business.

But Harry drank his seltzer standing by the side table, with no brandy, either; that was a good thing, no brandy. If he'd taken brandy, too, in his present excited condition, when he'd already certainly had quite as much as was at all good for him, Sir Thomas would have been justly and seriously angry. But, after all, Harry was a good boy at bottom, and knew how to avoid such ugly habits. He took his seltzer and his bedroom candle. Wilkins turned out the light in the room, and Harry went upstairs by himself immediately.

Then Wilkins turned the key in the library door, and the old gentleman began to reflect that this was really a most uncomfortable position for him to be left in. Suppose they locked him in there till to-morrow morning! Ah! happy thought; if the worst came to the worst he could get out of the library window and let himself in at the front door by means of his latch-key.
