Verbeck went back up the steps, crept through the house, and got out through the window by which he had entered, and which he now closed again. As he moved away from the house, an officer spoke to him.
"I thought that was you, Mr. Verbeck," he said. "Have you been inside?"
"Yes. There is nobody there now," Verbeck replied. "Is the door in the alley wall being watched?"
"Yes, sir," said the officer. "We've got good men scattered all around the place. If that big crook or any of his people come near here, they'll be nabbed!"
Verbeck hurried up the street and sprang into the roadster, smiling at Muggs' sour look.
"Drive to police headquarters, Muggs," he directed. "We'll stay there until a little before midnight, and then we'll go to the National Trust Company with the chief and his men, and watch for the Black Star. If he really attempts to rob that place to-night, he is going to be caught in the act."
"I'd like to get my two hands on him!" Muggs growled.
"Perhaps you'll have the chance," Verbeck said.
"If I do," Muggs said, "you can bet that the big crook will have a sore throat for a month!"
