"You are very kind. I shall not hesitate to accept any position you consider me fitted for. I will write to the bookseller to-morrow and tell him."

The inspector paused for a moment, tapping his desk with his knuckle, as if endeavouring to make up his mind to what use he could put George.

"I have a very ticklish affair on to-night—an affair of so much risk that I hardly like to ask you to take part in it as a start. But if you care to," he went on thoughtfully, "I am quite willing to take you with me, although I quite meant going alone. But you must decide at once."

"Make your mind easy," exclaimed George, his eyes glistening at the prospect of adventure. "Whatever it is, if you think I can be of assistance, I am with you."

The inspector eyed the keen, eager face with approval.

"So be it, then! Here, put this in your pocket," he said, handing him a revolver. "We will start at once."
