Morris, however, was an old hand at his business, and not a clumsy one. He stepped into his bedroom, which was darkened, and going to the window stood there watching. Presently he saw the three dark figures, unrecognizable at the distance, creep along the fives-court, dash across to the cloister that led from Standerland to the Schoolhouse, and then disappear behind the clump of trees at the corner. Confident that he had heard some one leaving his own dormitory, the master then made his rounds, and surely enough found that Deering, Lawrence and Wilson were missing. Curiously enough Tony’s happened to be the last room that he entered, and when he found his bedroom empty, thus being sure that the three he had seen were accounted for, he neglected to look into Carroll’s room, and returned to his study to wait for their return.

About ten o’clock as he sat before his fire, meditating the course of his action, a rap sounded on the door, and in response to his invitation, Doctor Forester came in.

“Ah, Morris,” said the Head Master, coming forward and standing with his back to the fire, “I am sorry to disturb you at this time of night; but there is mischief afoot, and perhaps you can help me catch the offenders.”

Morris looked at the Doctor attentively, but for the moment did not volunteer his information.

“This afternoon,” continued the Head, “Maclaren found an old shanty back of the Third Ridge, rigged out with the paraphernalia of a poker game. It has evidently been in use, and from the character of the débris, he thinks, by some of our boys. Maclaren supposes that some of your boys have been getting out at nights, and may be the culprits. Is that possible?”

“Yes,” answered Morris, “quite possible. I should not have said so an hour ago, for I keep a close watch upon that sort of thing, or at least I try to; but as a matter of fact three of my boys are missing at this moment.”

“Who are they?” asked the Doctor sharply.

“Lawrence, Deering and Wilson.”

“What! they are the last boys in the School that I should be inclined to suspect of that sort of thing, though I regret to say, Maclaren has some evidence that I fear implicates Deering. Have you any idea that they are gone to the Woods?”

“I fear they have, sir. I heard a noise in the hallway a half-hour ago, and slipped out to see what it was. For the moment I supposed I had been mistaken, but a little later from my bedroom window I saw three boys disappear back of the Schoolhouse. I did not know who they were until I had made my rounds, which was just a few minutes ago.”
