The Mystery of a Hansom Cab by Fergus Hume

There was not much sleep for Brian that night. He left Madge almost immediately, and went home, but he did not go to bed. He felt too anxious and ill at ease to sleep, and passed the greater part of the night walking up and down his room, occupied with his own sad thoughts. He was wondering in his own mind what could be the meaning of Roger Moreland's visit to Mark Frettlby. All the evidence that he had given at the trial was that he had met Whyte, and had been drinking with him during the evening. Whyte then went out, and that was the last Moreland had seen of him. Now, the question was, "What did he go to see Mark Frettlby for? " He had no acquaintance with him, and yet he called by appointment. It is true he might have been in poverty, and the millionaire being well-known as an extremely generous man, Moreland might have called on him for money. But then the cry which Frettlby had given after the interview had lasted a short time proved that he had been startled.

Madge had gone upstairs and found the door locked, her father refusing her admission. Now, why was he so anxious Moreland should not be seen by any one? That he had made some startling revelation was certain, and Fitzgerald felt sure that it was in connection with the hansom cab murder case. He wearied himself with conjectures about the matter, and towards daybreak threw himself, dressed as he was, on the bed, and slept heavily till twelve o'clock the next day. When he arose and looked at himself in the glass, he was startled at the haggard and worn appearance of his face. The moment he was awake his mind went back to Mark Frettlby and the visit of Roger Moreland.
