“You compel me to point out to you the situation you are in, Miss Neobard,” I continued. “A death has taken place, the police have inquired into it, and they have found cause for suspicion against certain persons. Lady Violet Bredwardine was one of those persons; you were another. Her innocence has now been proved. Yours only rests on your own assertion--or rather it may rest, because so far you haven’t actually asserted it. Therefore, you have the strongest possible motive for trying to throw suspicion on someone else; and you have been doing so all along. Now at last you have made a direct charge, and backed it up by stating what you say you saw through a curtain. I ask you again if you are certain of what you say, and I ask you to be careful.” Sarah Neobard’s face underwent a succession of changes while she listened, from amazement to wrath and from wrath to abject fear. Tarleton put the crown on her discomfiture. “Although we are not policemen, and this is not a formal charge, Dr. Cassilis is right to caution you,” he said firmly. “I shall feel at liberty to report whatever you say to the police.” The tables were completely turned. The triumphant accuser found herself all at once standing in the dock. She gave us both a long deep look of despairing hatred and dread. Then, with lips tightly closed, she got up and walked out of the room and out of the house. My chief gratified me with a nod and smile of approval. “You did that very well, Cassilis; I congratulate you. I think that young woman’s teeth have been drawn pretty effectually. It would never have done for her to be going about accusing the police of trying to hush up the case. She would have got some paper to take up her story, and there would have been the devil to pay.” “Do you think there is any chance that she was mixed up in the business?” I asked with hesitation. Evidently the specialist was displeased by the question. “It is not my practice to speculate, as I think I have told you. I prefer to confine myself to reasoning on the evidence before me. At present the evidence points to this death being due to a certain drug, which must have been administered during the dance by some person who was present, and who had a motive for rendering Weathered insensible--the death may have been due to his or her ignorance of the power of the drug. We now have direct evidence, which may be true, that the drug was put into his coffee by the dancer disguised as Zenobia, and we have further evidence that that costume was supplied to Lady Violet Bredwardine about a year ago, and was regularly worn by her in the Domino Club. “Add to that the appearance of her name in the list of suspects compiled from Weathered’s diary and the Club register, and the story we have just heard of her being pursued by Weathered and persecuted with attentions which she resented. It is a case on which very few juries would hesitate to convict.
