Secrets of the Heart — Candace Camp

SHE NEVER EXPECTED TO LOVE AGAIN...
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 felt she'd gotten what she deserved: a loveless marriage to a cold, enigmatic husband. She was wrong.

BUT 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?
