The Counterfeit Scoundrel by Lorraine Heath

Bestselling author Lorraine Heath begins a compelling new spin-off series, The Chessmen: Masters of Seduction, centering around three heroes—Knight, Bishop, and Rook—who play to win at any cost.

Born into an aristocratic family, yearning for a life beyond Society’s strictures, Marguerite “Daisy” Townsend is an enterprising sleuth. Hired to obtain proof of a wife’s infidelity, she secures a position in the household of the woman’s lover, never expecting to be lured into the seductive blackguard’s arms herself.
Devilishly handsome, David Blackwood, known widely as Bishop, quickly realizes the enticing maid is interested in far more than dusting. She aims to uncover his sins. Although tempted by the dangerous beauty, he can’t risk her learning the truth: his affairs are chaste. As a boy who witnessed his mother’s abusive relationship, Bishop now helps desperate wives escape unhappy marriages.
Yet when he is accused of murdering the husband of a “paramour,” he is forced to seek Daisy’s assistance in proving his innocence. As their perilous search draws them into a web of deceits, they can no longer deny their simmering desire. Once secrets are revealed, will Daisy’s counterfeit scoundrel give up the scandalous games he plays and surrender his heart into her keeping?
