One of the men he recognized as Darwin.
The man’s companion he had never seen before.
He could not get near enough to the men to hear their conversation.
At the corner of Fifty-second Street, the men separated, and Darwin started in an easterly direction.
Carter decided to follow him, and he gave up the idea of going home.
Darwin reached the east side of town, and turned into Second Avenue.
“What business has he over here?” the detective asked himself, as he kept on the trail of his quarry.
Between Forty-first and Fortieth Streets Darwin halted under a street lamp.
From his pocket he took a slip of paper, consulted it, and then went along examining the numbers of the houses.
Carter stopped in the doorway of the corner store and watched him.
