Liz Carlyle, bestselling author of <I>The Devil You Know</I> and <I>A Deal With the Devil,</I> continues her devilish streak with this sensual regency romance. <P> By day, Sidonie Saint-Godard is a quietly elegant young widow who teaches deportment to the unpolished daughters of London's nouveau riche. By night, she is someone altogether different.... <P> The notorious Black Angel -- so called for her lusciously located angel tattoo -- ruthlessly takes from powerful men who exploit, and gives to those who suffer at their hands. Always in disguise, she has eluded capture and her identity remains a mystery.... <P> The Marquess of Devellyn, one of the least noble noblemen in town, uses and discards women as he pleases. But when the Black Angel entices him into her bed, ties him up, and pilfers his most valued possession, she may have gone too far. This time, Devellyn tells her, she'll have the devil to pay. And he definitely means to collect.
