"He wasn't more than a hundred feet above us when he spoke. What can it be? He can't be in an airplane, or we'd hear the roar of the engine!"
"And his band is probably looting the vault of the trust company right now, or has looted it!" Verbeck said.
He ran quickly across the street, and Muggs and the chief followed at his heels. They knocked on a rear door of the building, and it was opened at once.
"Everything all right?" the chief asked.
"Nothing doing yet, chief," replied the detective who had opened the door.
"We'll take a look and make sure," the chief said. "I don't like this business at all!"
They went through a corridor and found the two watchmen. They had the lights in the vault room switched on.
"That vault hasn't been touched," Verbeck said, "unless they have tunneled from beneath. The door hasn't been opened."
"That crook was wise," the chief declared. "He knew that we were here waiting for him. How he found it out is more than I can tell—some of Sheriff Kowen's carelessness, I suppose."
A detective came running toward them through the corridor.
"Chief!" he shrieked. "Sergeant just came from headquarters! He says that the Black Star's gang is looting the First National—just got the alarm!"
