The naturalist introduced himself and his friends and then lost no time in getting to the point. He told of the theft in the freight yard, then of finding the attorney’s card.

“Naturally we resolved to hunt you up,” he said. “It is entirely possible that this thief has been to see you about buying specimens from him. Of course, you probably did not in the least suspect him. Or, if this is not the case, he got your card from some other source.”

Mr. Jordan was silent for several moments, as if in deep thought. Finally he turned to the others.

“I think I know the very man who stole them,” he announced.

“Good!” cried Joe impulsively.

“A very well-dressed chap,” the lawyer resumed, staring hard at the floor. “He came here about a month ago and said he dealt in all descriptions of specimens. But there was something about him that aroused my suspicions at once. Perhaps it was the way he acted. At any rate, I didn’t trust him. Appeared to be one of these, ah, slick, well-dressed rascals that you see so much of. I told him I desired nothing at present but rare specimens from Africa. He wore a blank look for a minute; then suddenly he gave a start and turned to me with a queer smile. ‘I’ll find you something,’ he said. ‘I think I know where I can get exactly what you want.’ I gave him one of my cards.”

“Perhaps that’s the very man we’re looking for,” said Bob. “Possible, anyway. Has he called you yet?”

“No. But if we think correctly, he may very soon now. Of course, though, he might wait till after the news of the robbery gets in the papers and has died down a bit.”

Mr. Holton shook his head.

“I’m of the opinion that he will sell those specimens before the news gets in the papers,” the naturalist said. “Perhaps he will pick today to do it. The sooner he gets them off his hands, the better chance he’ll have to get away without being found out.”
