"Give them to me."

The books were passed over, and Homer Bulson drew from his vest pocket a small roll of bills. He handed over a five to George Van Pelt.

"Now begone with you," he said sourly. "And don't ever come near me again for another order."

"Don't worry, I won't come," answered the book agent. "You are too hard a customer to suit."

He pocketed the money and rejoined Nelson on the sidewalk. Then both started to walk away.

As they did so our hero glanced across the way and saw, in a window of the house opposite, the young lady who had offered her assistance after Billy Darnley had robbed him.

She recognized him and smiled, and he promptly touched his hat respectfully.

Homer Bulson saw the act and so did George Van Pelt, and both stared at Nelson.

"Whom did you see?" asked Van Pelt, as they walked down the street.

"A lady who once offered to help me," said Nelson. "She was in that house. She has left the window now."
