A man controlled by his desires . . . 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 St. Giles like the back of her hand-she's spent a lifetime caring for its inhabitants at the foundling home her family established. Now that home is at risk . . . A woman haunted by her past . . . Caire makes a simple offer-in return for Temperance's help navigating the perilous alleys of St. Giles, he will introduce her to London's 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 cold calculation soon falls prey to a passion that neither can control-one that may well destroy them both. A bargain neither could refuse.
