Infamous for his wild, sensual needs, Lazarus Huntington, Lord Caire, is searching for a savage killer in St. Giles, London's most notorious slum. Widowed Temperance Dews knows the area like the back of her hand--she cares for its children at the foundling home her family established. Now that home is at risk... Caire makes a simple offer--in return for Temperance's help navigating the perilous alleys of St. Giles, he will introduce her to high society so that she can find a benefactor for the home. But Temperance may not be the innocent she seems, and what begins as a cold bargain soon falls prey to a passion neither can control--a passion that may well destroy them both.
