We could not leave her lying wounded upon the floor.”

“How long have you been here, doctor?”

“Since four o'clock.”

“Anyone else?”

“Yes, the constable here.”

“And you have touched nothing?”

“Nothing.”

“You have acted with great discretion. Who sent for you?”

“The housemaid, Saunders.”

“Was it she who gave the alarm?”

“She and Mrs. King, the cook.”

“Where are they now?”

“In the kitchen, I believe.”

“Then I think we had better hear their story at once.”

The old hall, oak-panelled and high-windowed, had been turned into a court of investigation. Holmes sat in a great, old-fashioned chair, his inexorable eyes gleaming out of his haggard face. I could read in them a set purpose to devote his life to this quest until the client whom he had failed to save should at last be avenged. The trim Inspector Martin, the old, grey-headed country doctor, myself, and a stolid village policeman made up the rest of that strange company.

The two women told their story clearly enough. They had been aroused from their sleep by the sound of an explosion, which had been followed a minute later by a second one. They slept in adjoining rooms, and Mrs. King had rushed in to Saunders. Together they had descended the stairs. The door of the study was open and a candle was burning upon the table. Their master lay upon his face in the centre of the room. He was quite dead. Near the window his wife was crouching, her head leaning against the wall. She was horribly wounded, and the side of her face was red with blood. She breathed heavily, but was incapable of saying anything. The passage, as well as the room, was full of smoke and the smell of powder. The window was certainly shut and fastened upon the inside. Both women were positive upon the point. They had at once sent for the doctor and for the constable. Then, with the aid of the groom and the stable-boy, they had conveyed their injured mistress to her room. Both she and her husband had occupied the bed. She was clad in her dress—he in his dressing-gown, over his night clothes. Nothing had been moved in the study. So far as they knew there had never been any quarrel between husband and wife. They had always looked upon them as a very united couple.

These were the main points of the servants' evidence. In answer to Inspector Martin they were clear that every door was fastened upon the inside, and that no one could have escaped from the house. In answer to Holmes they both remembered that they were conscious of the smell of powder from the moment that they ran out of their rooms upon the top floor. “I commend that fact very carefully to your attention,” said Holmes to his professional colleague. “And now I think that we are in a position to undertake a thorough examination of the room.”

The study proved to be a small chamber, lined on three sides with books, and with a writing-table facing an ordinary window, which looked out upon the garden.
