"I certainly do."
"When?"
"At once. Before they can find time to learn more than they already know," Nick declared. "I’ll pay Sadie Badger my promised visit within half an hour."
"But where do I fit in?" Chick inquired. "How can I aid you to the best advantage?"
Nick gazed thoughtfully at the floor for several moments. Then, abruptly looking up, he said quickly:
"Listen. I’ll tell you how."
Precisely half an hour later, as Nick had predicted, a roughly clad man, a perfect likeness of Sadie Badger’s partner in crime the previous night, entered the vestibule of the Lexington Avenue flat and pressed the electric bell.
At just about the same time, unobserved by any of the few pedestrians then in that locality, a second man stole into an alley leading to the rear of the brick block, and sought the gloomy yard back of the third house.
This second man was Chick Carter.
