From back cover:

On the eve of her wedding to Michael Trent, The Earl of Westhampton, Rachel Aincourt tried to elope with another man--only to be unceremoniously returned to her fiance by her strong-willed father. Burdened by guilt and shame, Rachel feld she'd gotten what she deserved: a loveless marriage to a cold, enigmatic husband. She was wrong.

Fate had other plans.

Behind Michael's proper demeanor lay a man who thrived on danger and intrigue--and now he'd been drawn into one of Bow Street's toughest cases. When the crime turned into a murder that involved Rachel, Michael found a new way to employ his mastery of disguise: seducing the wife he secretly loved. But would he finally be able to win her heart...or would he destroy his last chance for happiness?
