Jarvey leaped to his feet. "She's dead--she's murdered!" he shrieked. "I see her all covered with blood. Oh--mother--oh, I want my mother!" and down he dropped on the floor again, kicking and screaming.

The boy was scared out of his life, and Fritz laid hold of him, while the other servants, headed by the valiant cook, ran up the stairs and burst into Madame's sitting-room, which was on the ground floor, and no great distance from the front door. The next moment they were out again, all shrieking murder and calling loudly for the police. The sleeping boarders took the alarm, and in the lightest of attire appeared on the stairs with white faces. The terrible word shrieked by a dozen voices through the silent house curdled the blood in their aged veins. What with the early hour, the fog, the gas, and the crying of the servants, it was like a nightmare.

An hour later the police were in the house, summoned by Miss Bull, who alone of the boarders retained her head. As Margery, who was next in command after her aunt, could not be brought to do anything, Miss Bull took charge. It was Miss Bull who first ventured into the sitting-room where Madame, huddled up in a chair drawn to the table, lay face downward in such a position as to reveal a gaping wound in her neck. And it was Miss Bull who sent the servants back to the kitchen, who closed the door of the death-chamber, and who told Jarvey to fetch the nearest policeman. Consequently it was Miss Bull whom the inspector addressed, as she seemed to be the sole person in authority. Mrs. Taine retreated to her bedroom with a prayer-book, Mr. Granger went for a walk in the fog, Margery sat in a stupor, her eyes dull and her slack mouth awry. The little old maid, from being a nonentity, became a person of first-class importance. She displayed perfect tact and self-control in dealing with the terrified old men and women, and no one would have given her credit for such generalship. But the hour had come for Miss Bull to assert herself, and she proved to be equal to the occasion.

"Now, then," said the inspector, when he had posted his men and was alone with Miss Bull in the drawing-room, "what do you know of this?"

Miss Bull, her face white and drawn, her eyes sharper than ever, and her manner perfectly composed, shook her head. "I know absolutely nothing," she said in her monotonous voice. "Last night we had our usual reception, but it broke up at ten o'clock. Madame dismissed the guests at that hour, and stood in the doorway to do so. I retired to my bedroom with Madame's niece, and after a game of 'Patience' I went to bed."

"Does Mrs. Jersey's niece sleep with you?"

"Margery? No! She sleeps in a room above. It was a few minutes to eleven when she left me. I was in bed shortly after the clock struck the hour. I am sure Margery had nothing to do with it. She was quite devoted to her aunt, and as the poor girl has no money, I don't know how she will live now that Madame is dead."

The inspector thought for a moment. He was a tall, thin man, rather military in appearance, and with a wooden, expressionless face, which he found of great service in hiding his thoughts when examining those he suspected. He certainly did not suspect Miss Bull, and seemed inclined to make her his coadjutor. In proof of this he made her accompany him to the room wherein Mrs. Jersey lay dead.

"It's not far from the front door," mused Inspector Quex. "Could any one have entered?"

"No, I am sure of that," put in Miss Bull, emphatically. "Madame always locked the front door every night herself and kept the key. It could not be opened in the morning until she chose."
