"So you have decided to turn against me—after spending a hundred and fifty thousand of my money. Well, that's your affair of course. I hope you know where you're going to get more. This was a clumsy trap to expect to take the old fox in. Tell the young secretary he will have to do better than this if he expects to make that great reputation he is dreaming of. Like most young men he is prone to go of at half cock. Tell him that he had better be sure that he has anything against me before he calls in the police. But give him and the Third Deputy Commissioner my regards. They are waiting in the bar.

"Cordially yours,
"Mr. B."

Mr. B's taunting letter was a bitter dose for Jack's pride to swallow. Jack was young and very human, and it was only natural he should have been a little puffed up by his preliminary successes in a task that might well have daunted an experienced detective. And then to discover after all that his crafty adversary had only been playing with him, that he was aware of all his movements—well, Jack ground his teeth a bit. But the effect on the whole was salutary. The letter rebuked Jack's vanity, and steeled his resolution.

"I was a fool!" he told himself. "I didn't give the old boy credit for ordinary horse sense. Well, I won't make the same mistake again. I can't do anything more in my own character, that's certain. He has a perfect line on me as Bobo's secretary. But he doesn't know anything about Pitman yet—or young Henry Cassels, the student at Barbarossa's school. I'll get him yet."

The affair of the letter resulted in the swift break-up of Mrs. Cleaver's establishment. Jack did not see her again. He instructed the bank to pay her two hundred dollars weekly. She rented her house and departed—for an extensive trip through the South, it was given out.

Miriam disappeared too. Jack hoped that his mind would now be relieved of any further anxiety concerning her designs on Bobo. She would naturally suppose Jack thought, that in the general expose her connection with Mr. B. would be made known to Bobo, and she would scarcely have the effrontery to pursue him further. But Jack underrated that young lady's hardihood, as will be seen.

As a matter of fact Jack did not feel that it was necessary to explain to Bobo the whys and wherefors of what had happened. He had no confidence in Bobo's discretion. He ascribed Mrs. Cleaver's sudden departure to her well-known capriciousness. Bobo was a bit dazed by the change in the situation, and broken-hearted at the seeming loss of Miriam.

"Why don't I hear from her!" he cried a hundred times a day. "There wasn't any trouble the last time I saw her. You know, we went to the theater together, and you and Clara had dinner at home. When we got home Clara had gone to bed with a headache, but you were there waiting for us, and the three of us had a rabbit together, all as jolly as possible."
