Now Lady Sellingworth, as all her friends and many others knew, possessed an extremely valuable collection of jewels, and seldom, or never, moved far without taking a part of the collection with her. She loved jewels, and usually wore them in the evening, and as she was often seen in public--at the opera and elsewhere--her diamonds, emeralds, sapphires and pearls had often been admired, and perhaps longed for, by strangers. When she went to Paris on this occasion she took a jewel-case with her. In it there were perhaps fifty thousand pounds’ worth of gems. Her maid, a woman who had been with her for years, was in charge of the case except when Lady Sellingworth was actually in the train. Then Lady Sellingworth had it with her in a reserved first-class carriage for the whole of which she paid. The journey was not eventful. But to Lady Sellingworth it was an adventure. The brown man was on the train with his thin, sardonic friend, and with the old woman Lady Sellingworth had seen with him in London. The sight of this party--she saw them stepping into the Pullman car as she was going to her reserved carriage--surprised her. She had expected that the stranger would travel alone. As she sat down in her corner facing the engine, with the jewel-case on the seat next to her, she felt an obscure irritation. A man in search of adventure does not usually take two people--one of them an old woman in a black wig--with him when he sets out on his travels. A trio banishes romance. And how can a woman be thrilled by a family party? For a moment Lady Sellingworth felt anger against the stranger. For a moment she wished she had not undertaken the journey. It occurred to her that perhaps she had made a humiliating mistake when she thought that the brown man wished, and intended, her to go to Paris because he was going. Her pride was alarmed. She saw plainly for a moment the mud into which vanity had led her, and she longed to get out of the train and to remain in London. But how could she account to her maid for such a sudden change of plans? What could she say to her household? She knew, of course, that she owed them no explanation. But still--and her friends? She had told everybody that she was going to Paris. They would think her crazy for giving up the journey after she was actually in the train. And she had seen two or three acquaintances on the platform. No; she must make the journey now. It was too late to give it up. But she wished intensely she had not undertaken it.
