Well, to go back. The very year after the little brown dog was brought to Kerfol, Yves de Cornault, one winter night, was found dead at the head of a narrow flight of stairs leading down from his wife's rooms to a door opening on the court. It was his wife who found him and gave the alarm, so distracted, poor wretch, with fear and horror -- for his blood was all over her -- that at first the roused household could not make out what she was saying, and thought she had gone suddenly mad. But there, sure enough, at the top of the stairs lay her husband, stone dead, and head foremost, the blood from his wounds dripping down to the steps below him. He had been dreadfully scratched and gashed about the face and throat, as if with a dull weapon; and one of his legs had a deep tear in it which had cut an artery, and probably caused his death. But how did he come there, and who had murdered him?

His wife declared that she had been asleep in her bed, and hearing his cry had rushed out to find him lying on the stairs; but this was immediately questioned. In the first place, it was proved that from her room she could not have heard the struggle on the stairs, owing to the thickness of the walls and the length of the intervening passage; then it was evident that she had not been in bed and asleep, since she was dressed when she roused the house, and her bed had not been slept in. Moreover, the door at the bottom of the stairs was ajar, and the key in the lock; and it was noticed by the chaplain (an observant man) that the dress she wore was stained with blood about the knees, and that there were traces of small blood-stained hands low down on the staircase walls, so that it was conjectured that she had really been at the postern-door when her husband fell and, feeling her way up to him in the darkness on her hands and knees, had been stained by his blood dripping down on her. Of course it was argued on the other side that the blood-marks on her dress might have been caused by her kneeling down by her husband when she rushed out of her room; but there was the open door below, and the fact that the fingermarks in the staircase all pointed upward.
