"That proves some boys from this school took it from the island," said the doctor. "Is the boat all right?"
"Yes, sir. I looked her over, and in the bottom I found this case."
As Siller spoke he handed over a small leather case, which was empty but smelt strongly of tobacco.
"A cigarette case!" cried the master of the school. "Could any pupil here have had that? They know that smoking is forbidden." He turned the case over in the light. "Here is a letter painted on the side. It is rather worn."
"It is an M," said Andrew Dale, after an examination. "Let me see, what pupils' names begin with M?" He mused for a moment. "Morrison, Morr, Merwell"
"Morrison went home yesterday, to be gone a week. Merwell said the motor boat was not near the island, and I certainly did not hear it."
"Plum just said Morr and some others were out in a rowboat," added Andrew Dale, quickly. "This may be his cigarette case."
"We'll question him."
