England, 1867: Miss Caroline Hardcastle has fully embraced her scandalous reputation--even though doing so cost her a chance for love. She would much rather bring aid to those ignored by society by writing for England's most infamous crime column. When Caro's dear friend is kidnapped, however, she is shocked to find an ally in Lord Valentine Thorn, the same man who broke her heart years ago. Refusing his help would be the height of foolishness, but can she trust Val to stand by her?

Val--the new Viscount Wrackham--is in an untenable position: His father is demanding he find a respectable bride to secure the succession. Yet when Caro's improper actions require her to marry for convenience, Val sees an opportunity to show her he's a changed man. As the two grow closer to unmasking the culprit, can he convince her to give their love a second chance--before death does them part?
