"She's looking out for her present," thought Tom, with a grin. "But that's none of my affair. If only she isn't after this overcoat!"

He heard the housekeeper approach the recess and pause for a moment in front of it. He hardly dared to breathe, fearing that he would surely be discovered.

"Well, I declare, if he hasn't gone and worn the very overcoat itself!" he heard Mrs. Green cry. "Just like him, and two good coats a-hanging here. Well, I suppose it's the warmest he's got, and he'll have a cold ride back, especially if he returns to-night." And so speaking Mrs. Green hurried away.

"A narrow shave, and no mistake," murmured Tom to himself, and listened until he heard a distant door close. Then all was quiet, save the distant murmur of the student's voices, coming from the sitting room.

Without losing more time, Tom left the recess and hurried to the door of the stone cell.

"Sam!" he called out softly. "Are you in there?"

"No; I'm in here," came in the voice of Tubbs. "And—I'm almost frozen to—to—death." The last words with a chattering of teeth that told only too plainly how the rich youth was suffering.

"Sorry for you, Tubby, really I am. But where is Sam?"

"In the—the storeroom. Oh, Rover, won't you please ask Mr. Grinder to let me out? I'll freeze to death here, I know I will!"

"I'll do what I can. But he won't let you out. He isn't that kind of a fellow."
