"He's an agent of some sort," said the girl, "but I am sure you don't want me to discuss his business. And now I must go, doctor, if you will excuse me." "One moment," he begged. "I have a cab here. Won't you come and have tea somewhere?" "Where is somewhere?" she asked. "The Grand Alliance?" he suggested. She nodded slowly. CHAPTER VIII THE CRIME OF THE GRAND ALLIANCE The hotel and the cafe of the Grand Alliance was London's newest rendezvous. Its great palm-court was crowded at the tea-hour and if, as the mysterious Mr. Beale had hinted, any danger was to be apprehended from Dr. van Heerden, it could not come to her in that most open of public places. She had no fear, but that eighth sense of armed caution, which is the possession of every girl who has to work for her living and is conscious of the perils which await her on every side, reviewed with lightning speed all the possibilities and gave her the passport of approval. It was later than she had thought. Only a few tables were occupied, but he had evidently reserved one, for immediately on his appearance the waiter with a smirk led him to one of the alcoves and pulled back a chair for the girl. She looked round as she stripped her gloves. The place was not unfamiliar to her. It was here she came at rare intervals, when her finances admitted of such an hilarious recreation, to find comfort for jangled nerves, to sit and sip her tea to the sound of violins and watch the happy crowd at her leisure, absorbing something of the happiness they diffused. The palm-court was a spacious marble hall, a big circle of polished pillars supporting the dome, through the tinted glass of which the light was filtered in soft hues upon the marble floor below. "Doctor," she said, suddenly remembering, "I have been reading quite a lot about you to-day." He raised his eyebrows. "About me?" She nodded, smiling mischievously. "I didn't know that you were such a famous person--I have been reading about the Millinborn murder." "You have been reading about the Millinborn murder?" he said steadily, looking into her eyes. "An unpleasant case and one I should like to forget." "I thought it was awfully thrilling," she said. "It read like a detective story without a satisfactory end." He laughed. "What a perfectly gruesome subject for tea-table talk," he said lightly, and beckoned the head-waiter. "You are keeping us waiting, Jaques." "Doctor, it will be but a few minutes," pleaded the waiter, and then in a low voice, which was not so low that it did not reach the girl. "We have had some trouble this afternoon, doctor, with your friend." "My friend?" The doctor looked up sharply. "Whom do you mean?" "With Mr. Jackson." "Jackson," said the doctor, startled. "I thought he had left." "He was to leave this morning by the ten o'clock train, but he had a fainting-fit. We recovered him with brandy and he was too well, for this afternoon he faint again."
