“If you do any work at all,” said the policeman coldly, “you’ll look in at my office, or you’ll wish you had when it’s too late.”

“Of course, of course. I shouldn’t dream of omitting any formality that may be usual. But I don’t fancy I shall break my vacation. By the way, one little thing. Have you any objection to my carving a ‘J’ on your front door?”

The policeman stared.

“On the inside. It won’t show. It’s just a whim of mine. If you have no objection.”

“I don’t want any of your——” began the policeman.

“You misunderstand me. It’s only that it means paying for a dinner. I wouldn’t for the world——”

The policeman pointed to the window.

“Out you get,” he said abruptly. “I’ve had enough of you. And don’t you forget to come to my office.”

Spike, still deeply mistrustful of the bulldog Rastus, jumped at the invitation. He was through the window and out of sight in the friendly darkness almost before the policeman had finished speaking. Jimmy remained.

“I shall be delighted——” he had begun, when he stopped. In the doorway was standing a girl—a girl whom he recognized. Her startled look told him that she too had recognized him.
