Amy made no response, but pocketed the money. She was moving away when the workman detained her.
"You understand what's expected? You'll keep quiet if anyone asks you how you make your money?"
"I haven't made much yet."
"You will, never fear, if my little plan goes through. Do I have your promise to keep silent?"
"Yes," Amy answered shortly. She jerked away from Mr. Hoges and hurried off through the park.
Penny was so absorbed in the little scene that she did not hear footsteps behind her. "Hello, Penny," a teasing voice greeted. "What are you doing here?"
Penny sprang up from the park bench, then laughed ruefully as she saw that it was Susan Altman who had spoken to her so unexpectedly.
"My! You surely startled me, Susan."
"What are you doing here all by yourself?"
"Oh, just watching the birds and squirrels and things."
