"She shivered violently, and said, 'No, I won't have him in the house.' After a time she decided to bring me to you." "And have you had that hallucination again?" I inquired. "It was not a hallucination," she answered, pouting her lips. "I will humour you," I answered. "Have you seen your father again?" "No, and I am not likely to." "Why do you think that?" "I cannot quite tell you--I think mother is in it. Mother is very unhappy about something, and she looks at me at times as if she were afraid of me." Here Miss Heathcote rose. "You said I was not to stay long," she remarked. "Now I have told you everything. You see that it is absolutely impossible for ordinary medicines to cure me, any more than ordinary medicines can cure mother of her awful dreams." "I did not know that your mother dreamt badly," I said. "She does--but she doesn't wish it spoken of. She dreams so badly, she cries out so terribly in her sleep, that she has moved from her old bedroom next to mine, to one in a distant wing of the house. Poor mother, I am sorry for her, but I am glad at least that I have had courage to tell you what I have seen. You will make it your business to find out the truth now, won't you?" "What do you mean?" I asked. "Why, of course, my father is alive," she retorted. "You have got to prove that he is, and to give him back to me again. I leave the matter in your hands. I know you are wise and very clever. Good-bye, good-bye!" The queer girl left me, tears rolling down her cheeks. I was obliged to attend to other patients, but it was impossible for me to get Miss Heathcote's story out of my head. There was no doubt whatever that she was telling me what she firmly believed to be the truth. She had either seen her father once more in the flesh, or she was the victim of a very strong hallucination. In all probability the latter supposition was the correct one. A man could not die and have a funeral and yet still be alive: but, then, on the other hand, when Mrs. Heathcote brought Gabrielle to see me yesterday, why had she not mentioned this central and principal feature of her malady? Mrs. Heathcote had said nothing whatever with regard to Gabrielle's delusions. Then why was the mother so nervous? Why did she say nothing about her own bad dreams, dreams so disturbing, that she was obliged to change her bedroom in order that her daughter should not hear her scream? "I leave the matter in your hands!" Miss Heathcote had said. Poor child, she had done so with a vengeance. I could not get the story out of my thoughts, and so uncomfortable did the whole thing make me that I determined to pay Dr. Mackenzie a visit. Mackenzie was a physician in very large practice at Brixton. His name was already familiar to me--on one or two occasions I had met him in consultation. I looked up his address in the Medical Directory, and that very evening took a hansom to his house. He happened to be at home. I sent in my card and was admitted at once.
