"It does seem impossible, doctor; but it is true. I have seen her myself," and he shuddered. "She has been stabbed to the heart." The doctor wiped his eyes. "Well, I must go up and see her," he said. "Poor child, poor child. No, you need not ring. I will go up by myself." Dr. Arrowsmith had attended the family for many years, and knew perfectly well which was Margaret's room. The old cook was standing outside the door of the drawing-room. "Here is the key, sir. I thought it better to lock the door till you came." "Quite right," the doctor replied. "Don't let any one up till Mr. Volkes comes. The servant said he was going for him. Ah, here is Harpur. That is right, Harpur; you had better come up with me, but I shouldn't touch anything if I were you till Mr. Volkes comes; besides, we shall be having the Chief Constable over here presently, and it is better to leave everything as it is." They entered the room together. "Dear, dear, to think of it now," the constable murmured, standing awe-struck at the door, for the course of his duty was for the most part simple, and he had never before been face to face with a tragedy like this. The doctor moved silently to the bed, and leant over the dead girl. "Stabbed to the heart," he murmured; "death must have been instantaneous." Then he touched her arm and tried to lift it. "She has been dead hours," he said to the constable, "six or seven hours, I should say. Let us look round. The window is open, you see. Can the murderer have entered there?" He looked out. The wall was covered with ivy, and a massive stem grew close to the window. "Yes," he went on, "an active man could have climbed that. See, there are some leaves on the ground. I think, Harpur, your best plan will be to go down and take your station there and see no one comes along or disturbs anything. See, this jewel-box on the table has been broken open and the contents are gone, and I do not see her watch anywhere. Well, that is enough to do at present; we will lock this room up again until Mr. Volkes comes." When they came downstairs, the cook again came out. "Please, sir, will you come in here? Ruth Powlett, Miss Margaret's maid, seems very bad; it was she who first found it out, and it's naturally given her a terrible shock. She came down looking like a mad woman, then she fainted off, and she doesn't seem to have any sort of consciousness yet." "Ruth Powlett! why, I have been attending her for the last three weeks. Yes, such a shock may be very serious in her case," and the doctor went in. "Have you any sal volatile in the house?" he asked, after he had felt her pulse. "There's some in the medicine chest, I think, sir, but I will soon see." She went out and presently returned with a bottle. The doctor poured a teaspoonful into a glass and added a little water. Then he lifted Ruth's head, and forced it between her lips. She gasped once or twice, and then slightly opened her eyes.
