In his own fashion the stranger introduced the new-comer to Rodney. "This is Dr. Emmett, my medical attendant. I left him behind me in Brighton because I am sick and tired of his society; yet here he is at Croydon before I am. How he does these things I do not understand. He's a most extraordinary man." Then, also after his own fashion, he made Rodney known to the new-comer. "Emmett, this is a valued friend of mine, whom I have met for the first time to-night. I know all about him, except his voice; and, do you know, he's never spoken once." Rodney, observing the new-comer, perceived, from something which was in the glance he gave him in exchange for his, that the position had altered. Rising, he moved out of the carriage, still without a word. The stranger made as if to follow him, but the doctor put out a detaining hand. The train started just as Rodney, having gained the platform, was closing the door. The last he saw of the interior of the compartment was that the stranger seemed to be warmly expostulating with his medical attendant. At Redhill Rodney had got into the front part of the train--which was for London Bridge--because he felt that between the City and Notting Hill he might have an opportunity of shaking the stranger off. Now, as the London Bridge coaches glided out of the station, he passed to the Victoria half of the train, which awaited an engine, lower down the platform. The doctor's fortuitous arrival on the scene had saved him, at least temporarily, from what might have been a serious predicament. CHAPTER XII MARKING TIME Rodney Elmore's rooms were within a short distance of Paddington Station. As his cab drew up at the house he saw that another hansom was already at the door. Since it was past midnight, its presence was suggestive; it betokened a visitor. The house being a small one, there was only one other lodger besides himself, and he occupied a modest "bed-sitting-room" on the upper floor. His instinct told him that the visitor was for himself. At that hour on Sunday night the fact was portentous. Opening the door with his latch-key, as he stepped inside a girl came hastening towards him from a room at the back, noiselessly, as if she did not wish to be overheard, rather a pretty girl, with fluffy, fair hair. She spoke in a whisper: "There's someone to see you--a lady. She would wait, although I told her I didn't know when you would be in." "What's her name?" "She said Miss Patterson."
