"But I want to land him right away!" the chief fumed. "Did you happen to read the morning paper? If this sort of thing keeps up, the mayor will be asking for my resignation, and I'll go out of office without having vindicated myself. Confound Kowen, anyway! Why couldn't he keep the crook when he had him? But for Kowen, the Black Star would be doing time in the big prison right now!"

"But he isn't—and it doesn't do any particular good to wail about it," said Verbeck. "The thing to do is to get him again. Made any plans?"

"I'm up in the air!" the chief complained. "What plans can I make? I've got men guarding the museum, and those millionaires' residences, and a few scattered near the jewelry establishments. And I'll hold men ready to go to any section of the city when we get an alarm. That is all I can do. If we knew where he was going to strike——"

A buzzer sounded, and the chief took up the telephone.

"Hello!" he called.

"That you, chief?"

"Yes."

"Ah, good morning. This is the Black Star! I have tapped a private line again, chief, to have a little chat with you! I've been resting for a couple of days, giving my men and women a holiday. But I'm eager to be busy again!"

"When I get my hands on you——" the chief began.

"Tut, tut! Why do you always grow violent when I do you the honor of calling you up?"
