"My word, you've a lot to learn. Now, weighing the evidence, does anything strike you?"

"No."

"You're a bright sort of sleuth-hound, aren't you! It seems to me I'm doing all the work on this case. I'll have to give you another leg-up. Considering the time when the quid disappeared, I should say that somebody in the dormitory must have collared it. How many fellows are there in Evans' dormitory?"

"I don't know."

"Cut along and find out."

The detective reluctantly trudged off once more.

"Well?" said Scott, on his return.

"Seven," said Pillingshot. "Counting Evans."

"We needn't count Evans. If he's ass enough to steal his own quids, he deserves to lose them. Who are the other six?"

"There's Trent. He's prefect."
