As she passed through the gate she was surprised to see someone lurking among the laurel bushes. It was certainly a man, and to the best of her belief Mr. Arthur Morton. Preoccupied with her own troubles, she gave no particular attention to the incident, but hurried on upon her errand.
When she reached the house she perceived to her surprise that the light was still burning in the study. She therefore tapped at the surgery door. There was no answer. She repeated the knocking several times without effect. It appeared to her to be unlikely that the doctor would either go to bed or go out leaving so brilliant a light behind him, and it struck Mrs. Madding that it was possible that he might have dropped asleep in his chair. She tapped at the study window, therefore, but without result. Then, finding that there was an opening between the curtain and the woodwork, she looked through.
The small room was brilliantly lighted from a large lamp on the central table, which was littered with the doctor's books and instruments. No one was visible, nor did she see anything unusual, except that in the farther shadow thrown by the table a dingy white glove was lying upon the carpet. And then suddenly, as her eyes became more accustomed to the light, a boot emerged from the other end of the shadow, and she realized, with a thrill of horror, that what she had taken to be a glove was the hand of a man, who was prostrate upon the floor. Understanding that something terrible had occurred, she rang at the front door, roused Mrs. Woods, the housekeeper, and the two women made their way into the study, having first dispatched the maidservant to the police-station.
At the side of the table, away from the window, Dr. Lana was discovered stretched upon his back and quite dead. It was evident that he had been subjected to violence, for one of his eyes was blackened and there were marks of bruises about his face and neck. A slight thickening and swelling of his features appeared to suggest that the cause of his death had been strangulation. He was dressed in his usual professional clothes, but wore cloth slippers, the soles of which were perfectly clean. The carpet was marked all over, especially on the side of the door, with traces of dirty boots, which were presumably left by the murderer. It was evident that someone had entered by the surgery door, had killed the doctor, and had then made his escape unseen. That the assailant was a man was certain, from the size of the footprints and from the nature of the injuries. But beyond that point the police found it very difficult to go.
There were no signs of robbery, and the doctor's gold watch was safe in his pocket. He kept a heavy cash-box in the room, and this was discovered to be locked but empty. Mrs. Woods had an impression that a large sum was usually kept there, but the doctor had paid a heavy corn bill in cash only that very day, and it was conjectured that it was to this and not to a robber that the emptiness of the box was due. One thing in the room was missing-- but that one thing was suggestive. The portrait of Miss Morton, which had always stood upon the side-table, had been taken from its frame, and carried off. Mrs. Woods had observed it there when she waited upon her employer that evening, and now it was gone. On the other hand, there was picked up from the floor a green eye-patch, which the housekeeper could not remember to have seen before. Such a patch might, however, be in the possession of a doctor, and there was nothing to indicate that it was in any way connected with the crime.
Suspicion could only turn in one direction, and Arthur Morton, the young squire, was immediately arrested. The evidence against him was circumstantial, but damning. He was devoted to his sister, and it was shown that since the rupture between her and Dr. Lana he had been heard again and again to express himself in the most vindictive terms towards her former lover. He had, as stated, been seen somewhere about eleven o'clock entering the doctor's drive with a hunting-crop in his hand.
