When the Rogue Returns by Sabrina Jeffries

Victor Cale never imagined that his sweet, shy bride, Isabella, would use her talents for creating exquisite imitation jewels criminally. But there’s no denying that her handiwork was used in the theft of the Dutch royal diamonds– right after Isa disappeared into the night.

Ten years later, Victor is sent to Edinburgh to investigate a wealthy baron’s mysterious bride-to-be… who turns out to be Isa, masquerading as an alluring widow. No longer the meek girl he once knew, Isa boldly asserts that it was Victor who abandoned her, after he helped steal the royal diamonds!

Piecing together the truth of the past reawakens their volatile passion, which burns hotter than ever. But with a decade of secrets between them, Victor and Isa must trust each other to bring the real thieves to justice– without getting burned themselves.
