His lordship laughed.

"You are asking a question which, a month ago, was on the lips of nine out of every ten Londoners. It is only within the last fortnight that we have learned who and what 'Klimo' is."

"And pray what is he?"

"Well, the explanation is very simple. He is neither more nor less than a remarkably astute private detective, who has succeeded in attracting notice in such a way that half London has been induced to patronize him. I have had dealings with the man myself. But a friend of mine, Lord Orpington, has been the victim of a most audacious burglary, and, the police having failed to solve the mystery, he has called Klimo in. We shall therefore see what he can do before many days are past. But, there, I expect you will soon know more about him than any of us."

"Indeed! And why?"

"For the simple reason that he has taken No. 1, Belverton Terrace, the house adjoining your own, and sees his clients there."

Simon Carne pursed up his lips, and appeared to be considering something.

"I trust he will not prove a nuisance," he said at last. "The agents who found me the house should have acquainted me with the fact. Private detectives, on however large a scale, scarcely strike one as the most desirable of neighbors--particularly for a man who is so fond of quiet as myself."

At this moment they were approaching their destination. As the carriage passed Belverton Street and pulled up, Lord Amberley pointed to a long line of vehicles standing before the detective's door.

"You can see for yourself something of the business he does," he said. "Those are the carriages of his clients, and it is probable that twice as many have arrived on foot."
