It seemed to Verbeck that the other man expressed surprise in the way his shoulders straightened and his head lifted, and for an instant Verbeck feared he had attempted too much. But the other only nodded that he understood, then saluted and backed out of the door. Two minutes later Muggs came in from the other room and reported that the crook had put robe and mask in the box outside, and had hurried away.
“I’ll get him!” Verbeck said. “He’ll stop on that corner and give the sign, and then I’ll follow him. I’ll learn who it is that’s helping the Black Star gather valuable information. We’ve got to stick to the game now, Muggs, old man!”
“I’d call the police——”
“Not yet! I’m going to play this game myself until it gets too hot for me. The Black Star challenged me, didn’t he? I’ll have plenty of evidence before I call in the police.”
“What about the chief crook in the other room? He’s conscious again.”
Verbeck paced the floor for a time, his head bowed, thinking.
“I have it!” he exclaimed at last. “You get out of here, Muggs, and hurry to the garage and get my car. Stop at the rooms and get that bunch of keys in the right-hand drawer of my desk——”
“The keys to the old place?”
“Yes. We’ll take the Black Star there, Muggs. Bring the car to the corner nearest this house, then hurry in and help with him. We’ve got to have it done before dawn. Hurry! That’s what we’ll do, Muggs! We’ll take the Black Star to the old house, and there you’ll guard him, while I play master crook in his mask and robe.”
