“ The essay subject this week had been “One man’s meat is another man’s poison”, and Clowes, whose idea of English Essay was that it should be a medium for intempestive frivolity, had insisted on his beginning with, “While I cannot conscientiously go so far as to say that one man’s meat is another man’s poison, yet I am certainly of opinion that what is highly beneficial to one man may, on the other hand, to another man, differently constituted, be extremely deleterious, and, indeed, absolutely fatal.”
Trevor was not at all sure how the headmaster would take it. ”

“ My dear chap, she identified them all, one after the other. The first was one of Clowes. She was prepared to swear on oath that that was the chap who had sent the letters. Then I shot a photograph of you across the counter, and doubts began to creep in. She said she was certain it was one of those two ‘la-ads’, but couldn’t quite say which. To keep her amused I fired in photograph number three—­Allardyce’s. She identified that, too. ”

“Half a second,” said Trevor, as he got up; “had the fellow a cap of any sort?”
“No. Bareheaded. You wouldn’t expect him to give himself away by wearing a house-cap?”
Trevor went over to the headmaster’s revolving this discovery in his mind. It was not much of a clue, but the smallest clue is better than nothing. To find out that the sender of the League letters had fair hair narrowed the search down a little. It cleared the more raven-locked members of the school, at any rate. ”
