'Who can have done such a thing?' she asked at last, in a half-mechanical way. 'You must be a better judge of that question than I,' answered Mr. Hale. 'Is there any one in this house inimical to your stepdaughter?' 'No one, that I know of.' 'We have two duties before us, Mrs. Darrell: the first, to protect our patient from the possibility of any farther attempt of this kind; the second, to trace the hand that has done this work. I shall telegraph to Leeds immediately for a professional nurse, to relieve Miss Crofton in the care of the sick-room; and I shall communicate at once with the police, in order that this house may be placed under surveillance.' Mrs. Darrell said not a word, either in objection or assent, to this. She seated herself by the table again, and began trifling idly with the writing materials before her. 'You will do what is best, of course, Mr. Hale,' she said, after a long pause; 'you are quite at liberty to act in this matter according to your own discretion.' 'Thanks; it is a matter in which my responsibility entitles me to a certain amount of power. I shall telegraph to Dr. Lomond, asking him to come down to-morrow. Whatever doubt you may entertain of my judgment will be dispelled when I am supported by his opinion.' 'Of course; but I have not expressed any doubt of your judgment.' We left her immediately after this--left her sitting before the table, with her restless hands turning over the papers. The servant who went in search of her at seven o'clock that evening, when dinner was served, found her sitting there still, with a sealed letter lying on the table before her; but her head had fallen across the cushioned arm of the chair--she had been dead some hours. There was a post-mortem examination and an inquest. Mrs. Darrell had taken poison. The jury brought in a verdict of suicide while in a state of unsound mind. The act seemed too causeless for sanity. Her strange absent ways had attracted the attention of the servants for some time past, and the evidence of her own maid respecting her restlessness and irritability for the last few months influenced the minds of coroner and jury. The letter found lying on the table before her was addressed to Angus Egerton. He declined to communicate its contents when questioned about it at the inquest. Milly progressed towards recovery slowly but surely from the hour in which I stopped the suspected medicine. The time came when we were obliged to tell her of her stepmother's awful death; but she never knew the attempt that had been made on her own life, or the atmosphere of hatred in which she had lived. We left Thornleigh for Scarborough as soon as she was well enough to be moved, and only returned in the early spring, in time for my darling's wedding.
