"Then I cannot help you."

Lewis was pushed to his wits' end. George Prattleton was walking on, but turned again and waited. He was not free from some inward wonder and agitation himself, remembering his own adventure of the past night.

"If I trust a secret to you, will you promise, on your honour, not to tell it again?" asked Lewis. "It's nothing much; only a lark, concerning one of us college boys."

"Oh, I'll promise," readily answered George Prattleton, who was rarely troubled with scruples of any sort, and used to be fond of "larks" himself; rather too much so.

"Well, then, I locked Harry Arkell in the church last night, and I want to go and see after him, for fear he should be dead of fright, or something of that, you know."

"In there all night? in the church all night?" stammered George Prattleton, as if he could not take in the meaning of the words.

"He went in to practise after school yesterday evening, and I turned the key upon him, and took it back to old Hunt's, and he has been in there ever since, fastened up with the ghosts. I did it only for a lark, you know."

George Prattleton's arms dropped powerless by his side, and his face turned of some livid colour between white and green. Would the previous night's exploit—his exploit—come out to the world through this miserable fellow's ill-timed "joke?" But all they could do now was to see after Henry Arkell.

They went back to the clerk's, and George Prattleton took the key from the hook.
