“No, but when we saw a stranger sneaking into the school, we should have had gumption enough to notify the authorities,” insisted Bart. “That’s where we were slow. I didn’t want to make it any worse. If we find the bracelet, all right; we won’t have to tell how silly we were.”

“And if we don’t find it—which is very likely to be the case—what then?” asked Fenn.

“Well, we didn’t take it, that’s certain,” decided Frank. “Neither by accident nor intentionally—did we take that bracelet.”

“Then the man we saw, did,” said Ned.

“Yes, and he’s far enough off by now,” observed Frank. “Fellows, I’ll bet he was the thief!”

“How could he be?” asked Bart. “He didn’t know the bracelet was in the cabinet. Besides, no ordinary person would think of looking among a lot of reptiles for anything valuable.”

“Well, if we don’t find it I think we’d better tell about the man,” was Fenn’s opinion.

“It will be too late then,” insisted Bart.

“Too late? Why?” Frank wanted to know.

“Because if we come back without the missing turtle and bracelet, and tell about having seen a mysterious man enter the school just before we did, on Friday night, every one will say we made up the story to shield ourselves. No, the best way, if we can’t find that diamond ornament, is to keep mum about the man.”
