“A smuggler? What do you mean?”

“Well, anyway, he’s probably a Chinese spy in disguise.”

Wild Willie laughed derisively. “Say, I’ve known Chink Towner all my life, and he’s no more a smuggler than the Chief is! Why he’s not even a Chinaman—we just call him Chink because he kind of looks that way. You better get these nutty ideas out of your head before you get hurt. It’s just like that time you told me that Leggy and all the other colored fellows in the kitchen were counterfeiters.”

Sherlock winced. This affair was another of his failures to discover a secret threat of Crime hanging over the heads of his fellow campers. One evening soon after the camp season had started, he had been listening outside the shack where these dusky young men lived, back of the ice-house, and had heard the whirr of machinery and the proud voice of Leggy, assistant cook, remarking: “Yas suh, dis here ma-sheen is sure goin’ to make lots o’ money for us all!” His hope of fame as a great detective was blasted next day in mess-hall, however, when that same Leggy announced that he had “brought a sewing-machine to camp with him and was prepared, for a nominal sum of money, to mend rips and tears in the campers’ clothing.”

“Never mind about that,” he said desperately. “People around this camp are going to be pretty glad they’ve got a live-wire detective on the job. Pretty soon you’ll wish you’d listened to me.”

“Why? What’s going to happen?”

“Some people around here will bear watching, that’s all!” Sherlock cast a meaning glance in the direction of Tent Ten, where the twins had set about clearing up the devastated tent and making up the bunks into a semblance of orderliness.

Wild Willie stared in unbelief, and again broke into a laugh. “You mean the Utway brothers? Say, if you take my advice, you’ll keep away from those two! Everybody knows they scrap with each other now and then, but if you try to tackle one of them, you’ll have both of them coming down on your neck! What have you got against them?”

“Well,” said Sherlock slowly, “Jake threw around my good camera-case, and Jerry dumped a whole bucket of water on me——”

“That’s no crime, is it? What’s mysterious about that?”
