Why, Dick must be mad. Even a schoolboy would have had more caution when so much depended on it. But none would suspect the real cause of the change. These horrible tales were no doubt being circulated everywhere! The conversation fell back into a less personal channel again after this; they talked of "risks," of some one who had only been "writing" a year and was doing seven thousand a week, of losses they had been "on," and of the uselessness of "writing five hundred on everything," and while at this point the train slackened and stopped--they had reached Dufferton. There was an opening of doors all along the train, and sounds of some inquiry and answer at each. The voices became audible at length, and, as he had expected, Paul found that the Doctor, not having discovered him on the platform, was making a systematic search of the train, evidently believing that he had managed to slip in somewhere unobserved. It was a horrible moment when the door of his compartment was flung open and a stream of ice-cold air rushed under the blue cloth which, fortunately for Paul, hung down almost to the floor. Some one held a lantern up outside, and by its rays Paul saw from behind the hanging the upper half of Dr. Grimstone appear, very pale and polite, at the doorway. He remained there for some moments without speaking, carefully examining every corner of the compartment. The two men on the seats drew their wraps about them and shivered, until at length one said rather testily--"Get in, sir; kindly get in if you're coming on, please. This draught is most unpleasant!" "I do not propose to travel by this train, sir," said the Doctor; "but, as a person entrusted with the care of youth, permit me to inquire whether you have seen (or, it may be assisted to conceal) a small boy of intelligent appearance----" "Why should we conceal small boys of intelligent appearance about us, pray?" demanded the man who had described his visit to Mincing Lane. "And may we ask you to shut that door, and make any communications you wish to make through the window, or else come in and sit down?" "That's not an answer to my question, sir," retorted the Doctor. "I notice you carefully decline to say whether you have seen a boy. I consider your manner suspicious, sir; and I shall insist on searching this carriage through and through till I find that boy!" Mr. Bultitude rolled himself up close against the partition at these awful words. "Guard, guard!" shouted the first gentleman. "Come here. Here's a violent person who will search this carriage for something he has lost. I won't be inconvenienced in this way without any reason whatever! He says we're hiding a boy in here!" "Guard!" said the Doctor, quite as angrily, "I insist upon looking under these seats before you start the train. I've looked through every other carriage and he must be in here. Gentlemen, let me pass, I'll get him if I have to travel in this compartment to town with you!"
