"There is a mystery; and we, _rather I_, am not to see Mr. Arthur at present. Well, I don't want to see him; but _I hold the clue_ to your little game, my fair second wife." Lucian Davlin went to the city, but he did not set a detective on the track of Celine Leroque. He chose his man, one who had served him before, and set him about something quite different. Then he returned, feeling quite satisfied and confident of success. CHAPTER XXXIV. A SLIGHT COMPLICATION. And what of Celine, or Madeline, as we may call her once more? She had said, when writing to Olive, that her stay in the city must be very brief. But even her strong will could not keep off the light attack of fever that was the result of fatigue and exposure to night breezes. And the morning following her arrival at the villa, found her unable to rise from her bed. Dr. Vaughan was summoned in haste, and his verdict anxiously waited for. "It was a slight fever attack," he said, "but the wearied-out body must not be hurried. It must rest." And he forbade Madeline to leave her room for a week at least, unless she wished to bring upon herself a return of her summer's illness. Much to his surprise and gratification, Madeline did not rebel, but replied, philosophically: "I can't afford to take any risks now; I will be good. But you must watch my interests." During the first day of her "imprisonment," as she laughingly called it, Clarence and Olive were put in possession of all the facts that had not already been communicated by letter. Upon one thing they were all agreed, namely, that it would be wise for Clarence to make another journey to Bellair. "They won't be able to accomplish much during the week that I must remain inactive," said Madeline. "But it will be safest to know just what they are about. Besides, I have reasons for thinking that Henry is growing dissatisfied, and it is to our interest to keep him where he is for the present. Had a suitable opportunity offered, I should have made him aware of my identity. But as it did not present itself, I left it with Hagar to inform him that he was serving me by remaining." Dr. Vaughan prepared to visit Bellair on the second day after the arrival of Madeline. But almost at the moment of starting there came a summons from one of his patients, who was taken suddenly worse. Thinking to take a later train he hastened to the sick man; but the hour for the last train arrived and passed, and still he stood at the bedside, battling with death. So it transpired that nearly three days had elapsed since the flitting of Celine Leroque, when Dr. Vaughan entered the train that should deposit him at dusk in the village of Bellair.
