To Lord Wydcombe's, in Curzon Street, I followed him on several occasions, for he had suddenly become very intimate with Wydcombe it appeared, and while I stood on the pavement outside that house I knew so well my thoughts wandered back to those brilliant festivities which Cynthia so often gave. One night, after Winsloe had dined there, I saw the brougham come round, and he and Cynthia drove off to the theatre, followed by Jack and Wydcombe in a hansom. On another afternoon I followed Winsloe to the Scarcliffs in Grosvenor Place, and later on saw him laughing with old Lady Scarcliff at the drawing-room window that overlooked Hyde Park Corner. He presented a sleek, well-to-do appearance, essentially that of a gentleman. His frock coat was immaculate, his overcoat of the latest cut, and his silk hat always ironed to the highest perfection of glossiness. Tibbie, of course, knew nothing of my patient watchfulness. I never went near my chambers, therefore Ellice and Parham certainly believed me dead, while as to Domville's hiding in Paris, I confess I doubted the truth of the statement of Tibbie's friend. If the poor fellow still lived he would most certainly have written to me. No! He was dead-- without a doubt. He had fallen a victim in that grim house of doom. Again and again I tried to find the gruesome place, but in vain. Not a street nor an alley in the neighbourhood of Regent Street I left unexplored, yet for the life of me I could not again recognise the house. The only plan, I decided, was to follow Parham, who would one day go there, without a doubt. I called on Mrs Parham at Sydenham Hill, and found that her husband was still absent--in India, she believed. Miss O'Hara, however, remained with her. What connection had the girl with those malefactors? I tried to discern. At all events, she knew their cipher, and they also feared her, as shown by their actions on that dark night in Dean's Yard. My own idea was that Parham was still away in the country. Or, if he were in London, he never went near Winsloe. The police were in search of him, as admitted by the inspector at Sydenham, therefore he might at any moment be arrested. But before he fell into the hands of the police I was determined to fathom the secret of that house of mystery wherein I had so nearly lost my life. For Tibbie's personal safety I was now in constant and deep anxiety. They were desperate and would hesitate at nothing in order to secure their own ends. The ingenuity of the plot to seize her in Dean's Yard was sufficient evidence of that. Fortunately, however, Tibbie had not seen my cipher advertisements.
