A Duke, the Spy, an Artist, and a Lie - Vanessa Riley - Bog

"For adventurous Jamaican heiress Cecilia Thomas, marrying charming military lieutenant Lord Gantry to save him from danger--and herself from mercenary suitors--was a painful mistake. Instead of a passionate life together, she's stranded at his chilly Mayfair mansion with his unaccepting family. Worse, she finds he is actually a spy dedicated to duty over wedlock--and secrets over trust. So when she hears her sister has been driven to her death, Cecilia is determined to expose the powerful man responsible. Assisted by The Widow's Grace, she flees to Covent Garden with a new identity. But can she elude her formidable husband--even as the desire between them continues to flare even hotter?"--
