"I wanted to be certain that my husband was really very ill," she said. "I wanted you to talk to him--I guessed he would confide in you; I thought it most probable that you would tell him that he was a victim of brain hallucinations. This would frighten him and would suit my purpose exactly. I also sent for you as a blind. I felt sure that under these circumstances neither you nor my husband could possibly suspect me." She was silent again, panting from exhaustion. "I have failed," she said, after a long pause. "You have discovered the truth. It never occurred to me for a moment that you would go into the room. He will recover now." She paused; a fresh attack of haemorrhage came on. Her breath came quickly. Her end was very near. Her dim eyes could scarcely see. Groping feebly with her hand she took mine. "Dr. Halifax--promise." "What?" I asked. "I have failed, but let me keep his love, what little love he has for me, before he marries that other woman. Promise that you will never tell him." "Rest easy," I answered, "I will never tell him." Sir Henry entered the room. I made way for him to kneel by his wife's side. As the grey morning broke Lady Studley died. Before my departure from the Grange I avoided Sir Henry as much as possible. Once he spoke of the apparition and asked if I had seen it. "Yes," I replied. Before I could say anything further, he continued:-- "I know now why it came; it was to warn me of my unhappy wife's death." He said no more. I could not enlighten him, and he is unlikely now ever to learn the truth. The following day I left Studley Grange. I took with me, without asking leave of any-one, a certain long black cloak, a small electric lamp, and a magnifying glass of considerable power. It may be of interest to explain how Lady Studley in her unhealthy condition of mind and body performed the extraordinary trick by which she hoped to undermine her husband's health, and ultimately cause his death. I experimented with the materials which I carried away with me, and succeeded, so my friends told me, in producing a most ghastly effect. I did it in this way. I attached the mirror of a laryngoscope to my forehead in such a manner as to enable it to throw a strong reflection into one of my eyes. In the centre of the bright side of the laryngoscope a small electric lamp was fitted. This was connected with a battery which I carried in my hand. The battery was similar to those used by the ballet girls in Drury Lane Theatre, and could be brought into force by a touch and extinguished by the removal of the pressure. The eye which was thus brilliantly illumined looked through a lens of some power. All the rest of the face and figure was completely covered by the black cloak. Thus the brightest possible light was thrown on the magnified eye, while there was corresponding increased gloom around.
