"Was the sweater there?"
"I didn't look."
Chub whistled softly.
"Bet you anything some fellow swiped it and wore it," he declared. "Let's go see if he put it back."
They hurried up to the dormitory and Roy unlocked his trunk, threw back the lid and opened the till.
"I thought I left it here on top," he muttered, diving through the contents of the till. "Maybe I put it underneath, though." Out came the till and out came most of the contents of the trunk. But there was no crimson sweater. Roy turned to Chub in distress.
"I don't care if they took it," he said, "but I hope they'll bring it back! I wouldn't lose that sweater for anything!"
"Lock your trunk again," said Chub, "and let's get out of here. Some one's coming. Let's go somewhere and think it over."
"If we only knew who was away from school yesterday afternoon," said Roy when they were once more under the trees.
"We know that Ferris and Burlen were," answered Chub suggestively. "They said so."
