"Why, Mullins says that some man from the fair came this morning, and wanted to see the headmaster. He says one of our fellows was up there last night, kicking up a fine shindy, and set his show on fire; and he means to find out who it is, and summon him for damages. Mullins told him he'd better call again later on, as Westford was at breakfast. My eye! I pity the chap who did it, if it's true, and he's collared."

The clang of the school bell ended the conversation, and Tinkleby rushed off to impart his news to other classmates.

The distressed look on Valentine's face deepened, but he said nothing.

"Pooh!" exclaimed Jack, sticking his hands in his pockets, and making the gravel fly with a vicious kick. "Let him come and say what he likes. What do I care?"

The school had reassembled after the usual interval, and the Sixth Form were sitting in their classroom waiting for the arrival of the headmaster. A quarter of an hour passed, and still he did not arrive. At length the door opened, and Mullins poked his head inside.

"Mr. Westford wants to see all those gentlemen who are in charge of the different dormitories—now, at once, in his study."

A murmur of surprise followed the announcement, as the boys indicated rose to their feet and prepared to obey the summons. On entering the study they found a shabby-looking man standing just inside the door, who eyed them all narrowly as they came in. The headmaster sat at his writing-table looking stern and troubled. The twelve prefects arranged themselves in a semicircle, and stood silently waiting and wondering what could have happened.

"You say this took place about a quarter past ten?"

"Yes, sir," answered the man, twirling his hat with his fingers. "As near as I can say, it must have been about a quarter a'ter ten."

"I have sent for you," continued Mr. Westford, turning to the group of senior scholars, "to know if any of the boys were absent from any of the dormitories at the usual bed-time."
