The Mystery of the Blue Train by Agatha Christie

asked Katherine, smiling as she rose from the table.
    The little man shook his head.
    “I never prophesy,” he declared pompously. “It is true that I have the habit of being always right - but I do not boast of it. Good-night, Mademoiselle, and may you sleep well.”
    Katherine went back along the train amused and entertained by her little neighbour.
    She passed the open door of her friend's compartment and saw the conductor making up the bed. The lady in the mink coat was standing looking out of the window. The second compartment, as Katherine saw trough the communicating door, was empty, with rugs and bags heaped up on the mat. The maid was not there.
    Katherine found her own bed prepared and since she was tired, she went to bed and switched off her light about half-past nine.
    She woke with a sudden start; how much time had passed she did not know. Glancing at her watch, she found that it had stopped.
    A feeling of intense uneasiness pervaded her and grew stronger moment by moment. At last she got up, threw her dressing-gown round her shoulders, and stepped out into the corridor. The whole train seemed wrapped in slumber. Katherine let down the window and sat by it for some minutes, drinking in the cool night air and trying vainly to calm her uneasy fears. She presently decided that she would go along to the end and ask the conductor for the right time so that she could set her watch. She found, however, that his little chair was vacant.
    She hesitated for a moment and then walked through into the next coach. She looked down the long, dim line of the corridor and saw, to her surprise, that a man was standing with his hand on the door of the compartment occupied by the lady in the mink coat. That is to say, she thought it was the compartment. Probably, however, she was mistaken. He stood there for a moment or two with his back to her, seeming uncertain and hesitating in his attitude. Then he slowly turned, and with an odd feeling of fatality, Katherine recognized him as the same man whom she had noticed twice before - once in the corridor of the Savoy Hotel and once in Cook's offices. Then he opened the door of the compartment and passed in, drawing it to behind him.
    An idea flashed across Katherine's mind. Could this be the man of whom the other woman had spoken - the man she was journeying to meet.
    Then Katherine told herself that she was romancing. In all probability she had mistaken the compartment.
    She went back to her own carriage. Five minutes later the train slackened speed.
    There was the long plaintive hiss of the Westinghouse brake, and a few minutes later the train came to a stop at Lyons.

    MURDER
    Katherine wakened the next morning to brilliant sunshine. She went along to breakfast early, but met none of her acquaintances of the day before. When she returned to her compartment it had just been restored to its daytime appearance by the conductor, a dark man with a drooping moustache and melancholy face.
    “Madame is fortunate,” he said, “the sun shines. It is always a great disappointment to passengers when they arrive on a grey morning.”
    “I should have been disappointed, certainly,” said Katherine.
    The man prepared to depart.
    “We are rather late, Madame,” he said. “I will let you know just before we get to Nice.”
    Katherine nodded. She sat by the window; entranced by the sunlit panorama. The palid trees, the deep blue of the sea, the bright yellow mimosa came with all the charm of novelty to the woman who for fourteen years had known only the drab winters of England.
    When they arrived at Cannes, Katherine got out and walked up and down the platform. She was curious about the lady in the mink coat, and looked up at the windows of her compartment. The blinds were still drawn down - the only ones to be so on the whole train. Katherine wondered a little, and when she re-entered the train she passed along the corridor and noticed that these two
