The House Of Silk

nothing is as it seems and that unless you help us, unless you can lift the curse that has fallen on this place, we are doomed.’
    ‘I beg of you, Miss Carstairs, to compose yourself.’
    ‘She is the cause of all this!’ The sister flung an accusatory finger in the direction of the house. ‘Catherine Marryat – for that was her name by her first marriage. She came upon Edmund when he was at his lowest ebb. He has always had a sensitive nature, even as a boy, and it was inevitable that his nerves would be unable to stand up to the ordeal he had been through in Boston. He was exhausted, infirm and – yes, in need of someone to take care of him. And so she threw herself at him. What right did she have, an American nobody with barely any money to her name? Out at sea, with days on board that ship, she spun a web around him so that when he returned home, it was too late. We could not dissuade him.’
    ‘You would have looked after him yourself.’
    ‘I love him as only a sister can. My mother too. And do not believe for a single minute that she died as a result of an accident. We are a respectable family, Mr Holmes. My father was a printseller who came to London from Manchester and it was he who opened the picture-dealership in Albemarle Street. Alas, he died when we were quite young and since then the three of us have lived together in perfect harmony. When Edmund announced his determination to ally himself with Mrs Marryat, when he argued with us and refused to listen to reason, it broke my mother’s heart. Of course we would have liked to see Edmund married. His happiness was all that mattered to us in the world. But how could he marry her? A foreign adventuress we had never met and who, from the start, was clearly interested only in his wealth and position, in the comfort and protection he could give her. My mother killed herself, Mr Holmes. She could not live with the shame and the unhappiness of this accursed marriage and so, six months after the wedding day, she turned on the gas tap and lay on her bed until the fumes had done their work and the kindness of oblivion had taken her from us.’
    ‘Did your mother communicate her intentions to you?’ Holmes asked.
    ‘She didn’t need to. I knew what was in her mind and I was hardly surprised when they found her. She had made her choice. This has not been a pleasant household from the day that the American woman arrived, Mr Holmes. And now this latest business, this intruder who has broken into our home and stolen Mama’s necklace, our most cherished memory of that dear, departed soul. It is all part of the same evil business. How do we not know that this stranger has not come here on her account rather than to pursue some vendetta against my brother? She was with me in the sitting room when he first appeared. I saw him from the window. Perhaps he is an old acquaintance who has followed her here. Perhaps he is more. But this is only the beginning of it, Mr Holmes. So long as this marriage continues, we will none of us be safe.’
    ‘Your brother seems perfectly content,’ Holmes responded, with a degree of indifference. ‘But setting that aside, what would you have me do? A man can choose whom he marries without the blessing of his mother. Or, indeed, of his sister.’
    ‘You can investigate her.’
    ‘It is none of my business, Miss Carstairs.’
    Eliza Carstairs gazed at him with contempt. ‘I have read of your exploits, Mr Holmes,’ she replied. ‘And I have always considered them to be exaggerated. You yourself, for all your cleverness, have always struck me as someone with no understanding of the human heart. Now I know that to be true.’ And with that, she wheeled round and went back into the house.
    Holmes watched her until the door had closed. ‘Most singular,’ he remarked. ‘This case becomes increasingly curious and complex.’
    ‘I have never heard a woman speak with such fury,’ I observed.
    ‘Indeed, Watson. But there is one thing I would particularly like to know, for I am beginning to see great danger in this situation.’ He glanced at the fountain, at the stone figures and the frozen circle of water. ‘I wonder if Mrs Catherine Carstairs is able to swim?’

    Holmes slept in late the next morning and I was sitting on my own, reading
The Martyrdom of Man
, by Winwood Reade, a book that he had recommended to me on more than one occasion but which, I confess, I had found heavy going. I
