"But I'd have no choice, really. I must have rest. My doctor orders it."
Jack smiled grimly at the thought of a crook threatened with nervous prostration as a result of overwork. These are rapid times that we live in! He cast about in his mind for the means to prolong the conversation.
"How do I know you're on the square?" he asked. "About quitting, I mean."
"Go see your friend Anderson to-morrow. You'll find him closed up. Mail your employer's check to the Eureka Protective Association. It will be returned to you by the post-office."
It seemed wise to Jack to appear to fall in with the other's suggestions. "I appreciate your friendliness in warning me," he said. "Do you mind if I ask you a question or two. Just natural, human curiosity, you know."
"Ask them and I'll see."
"How did you know I had been here in your office when you came. I had disturbed nothing."
"Perhaps I was there myself at the time."
"Impossible! I made sure of that."
The laugh sounded again. "Nothing is impossible! Think it over!"
