"You remember the sentry was upset—"
"Very upset."
"Somebody collared him from behind, and upset him into the ditch. They went in together, and the other man sat on his head."
"A touching picture. Proceed, friend."
"They rolled about a bit, and this sentry chap swears he scratched the man. It was just after that that the man sat on his head. Jones says he was a big chap, strong and heavy."
"He was in a position to judge, anyhow."
"Of course, he didn't mean to scratch him. He was rather keen on having that understood. But his fingers came up against the fellow's cheek as he was falling. So you see we've only got to look for a man with a scratch on his cheek. It was the right cheek, Jones was almost certain. I don't see what you're laughing at."
"I wish you wouldn't spring these good things of yours on me suddenly," gurgled Jimmy Silver, rolling about the wooden floor of the tent. "You ought to give a chap some warning. Look here," he added, imperatively, "swear you'll take me with you when you go on your tour through camp examining everybody's right cheek to see if it's got a scratch on it."
Kennedy began to feel the glow and pride of the successful sleuth-hound leaking out of him. This aspect of the case had not occurred to him. The fact that the sentry had scratched his assailant's right cheek, added to the other indubitable fact that Walton, of Kay's, was even now walking abroad with a scratch on his right cheek, had seemed to him conclusive. He had forgotten that there might be others. Still, it was worth while just to question him. He questioned him at Cove Reservoir next day.
"Hullo, Walton," he said, with a friendly carelessness which would not have deceived a prattling infant, "nasty scratch you've got on your cheek. How did you get it?"
