The clerk thumbed through a stack of letters before answering. "I don't remember the man but he'll probably call here sooner or later for he has two letters."

Penny retreated to her post near the door. It was tedious waiting.

"When I get to be a taxpayer I'll vote for chairs in every post office!" she thought.

Penny spent nearly the entire day waiting for George Hoges to appear. By nightfall she was so weary she could scarcely stumble home. She felt certain she would not have the fortitude to resume her watch the following day.

Mr. Nichols was amused when she told him of her unpleasant experience.

"A detective must learn to spend half of his time just waiting," he declared. "Why, I've handled cases where we assign men to watch a certain street corner. Perhaps they'll be required to keep it up for six months."

"That's a long time."

"Not if the man you're after comes along in the end."

"If I keep up my vigil even six days I'll have corns on the bottom of my feet," Penny sighed. "Everything considered, I don't believe I'm cut out to be a lady detective."

However, the following day found her again at her station in the post office. The task of waiting and watching seemed even more tiresome than before. When she came home late in the afternoon Mrs. Gallup offered scant sympathy.
