“As low as you can,” he answered; “I have excellent ears. If you would have the great kindness to get rid of that sottish friend of yours I should be exceedingly glad to have a little talk with you.”

“I have a cab outside.”

“Then pray send him home in it. You may safely trust him, for he appears to be too limp to get into any mischief. I should recommend you also to send a note by the cabman to your wife to say that you have thrown in your lot with me. If you will wait outside, I shall be with you in five minutes.”
