Wicked Intentions (Electronic book text)

Cold, clinical scientist Lord Grayston Kane is a man without passion or emotion. He lost his mistress - the only women he's ever loved - to a savage attack. Now he's vowed to find the murderer - even if it means haunting the worst streets of London nightly.
Miss Constance Dews believes in practicing Christian charity, not simply discussing it. The daughter of a nonconformist minister, she helps run a foundling home in St. Giles. She heartily disapproves of the humorless Lord Kane who seems to think everyone in St. Giles is either a thief, a prostitute, or worse. But when someone starts murdering the women of St. Giles, Camilla realizes that only Lord Kane can keep her - and her charges - safe.
