Mr. Melladew was rocking to and fro murmuring, "O, my Lizzie, my darling child! O, my poor, poor Lizzie!" We had spoken in low tones, and he evinced no consciousness of having heard what we said. During our conversation the reporter was jotting down notes unobtrusively. The conversation would doubtless have been continued had it not been for the appearance of other persons, following rapidly upon each other, policemen, and additional reporters, who had discovered that Mr. Melladew was in my house. The last to appear was Mrs. Melladew, who had heard rumours of the frightful crime, and who flew round to me, not knowing that her husband was in the room. What passed from that moment, while all these persons were buzzing around me, was so confusing that I cannot hope to give an intelligible transcript of it. I was, as it were, in the background, as one who had no immediate interest in the unravelling of the terrible mystery. It was a most agitating time to me and my wife, and when my visitors had all departed I felt like a man who had been afflicted by a horrible nightmare. How little did I imagine that the letter I had received by the early morning's post, and which I had in my pocket, was vitally connected with it, and that of all those present I was the man who was destined to bring the mystery to light! Before the day was over fresh surprises were in store for me in connection with the dreadful deed. Needless to say that the whole neighbourhood was in a state of great excitement; so numerous were my idle visitors that I was compelled to tell my wife to admit into the house no person but the Melladews, or relatives of theirs. In the afternoon, however, one visitor called who would not be denied. He sent in his card, which bore the name of George Carton, and I said I would see him. He was a young man, whose age I judged to be between twenty and twenty-five, well dressed, and remarkably good-looking. His manners were those of one who was accustomed to move in good society, and both his speech and behaviour during the interview impressed me favourably. I observed when he entered the room that he was greatly agitated. "I have intruded myself upon you, sir," he said, "because I felt that I should go mad if I did not speak to some person who was a friend of--or----" He could not proceed, and I finished the sentence for him. "Of the poor girl who has been so cruelly murdered?" He nodded his head, and, when he could control his voice, said, "You were an intimate friend of hers, sir?" "Mr. Melladew's family and mine," I replied, "have been on terms of friendship for many years. I have known the poor girl and her sister since their infancy." "I did not dare to call upon Mr. Melladew," he said, and then he faltered again and paused. "Are you acquainted with him?" I asked.
