“Miss Amelia had some great friends in Edinburgh, whom she had long wished to visit, her father’s crippled condition making this extremely difficult. A fortnight ago however, in response to a very urgent invitation, she at last decided to accept it, but in order to leave her father altogether comfortable, she advertised in the local paper for a respectable woman who would come to the flat every day and see to all the work, cook his dinner, make the bed, and so on. “She had several applications in reply to this advertisement, and ultimately selected a very worthy-looking elderly person, who, for seven shillings a week, undertook to come daily from seven in the morning until about six in the afternoon, to see to all Mr. Dyke’s comforts. “Miss Amelia was very favourably impressed with this person’s respectable and motherly appearance, and she left for Edinburgh by the 5.15 a.m. train on the morning of Thursday, 19th November, feeling confident that her father would be well looked after. She certainly had not heard from the old man while she was away, but she had not expected to hear unless, indeed, something had been wrong. “Miss Amelia was quite sure that something dreadful had happened to her father, as he could not possibly have walked downstairs and out of the house alone; certainly his crutches were nowhere to be found, but this only helped to deepen the mystery of the old man’s disappearance. “The constable, having got thus far with his notes, thought it best to refer the whole matter at this stage to higher authority. He got from Miss Amelia the name and address of the charwoman, and then went back to the station. “There, the very first news that greeted him was that the medical officer of the district had just sent round to the various police stations his report on the human remains found in Wembley Park the previous Saturday. They had proved to be the dismembered body of an old man between sixty and seventy years of age, the immediate cause of whose death had undoubtedly been a violent blow on the back of the head with a heavy instrument, which had shattered the cranium. Expert examination further revealed the fact that deceased had had in early life both legs removed by a surgical operation just above the knee. “That was the end of the prologue in the Lisson Grove tragedy,” continued the man in the corner, after a slight and dramatic pause, “as far as the public was concerned. When the curtain was subsequently raised upon the first act, the situation had been considerably changed. “The remains had been positively identified as those of old Mr. Dyke, and a charge of wilful murder had been brought against Alfred Wyatt, of no occupation, residing in Warlock Road, Lisson Grove, and against Amelia Dyke for complicity in the crime. They are the two people whom I am going to see this afternoon brought before the Beak at the Marylebone Police Court.” Chapter II
