The daughter of an earl, Tamar McKinnon should have lived a life of opulence as one of the Regency elite. Instead, her world is shattered when she is falsely accused of murdering her father. Escaping to London, she is rescued by an unlikely ally and trained in the art of thief-taking—the capture of wanted criminals—in the perilous city underworld.

Sinking into obscurity with a spirited group of friends, she is plunged back into danger when a seemingly straightforward case of a missing person becomes something more sinister.

Murder, kidnapping, bodysnatching... her determination to solve the case may lead her to the gallows. With her vicious brother hunting her and a troublesome duke on her tail, Tamar must use all her courage to protect her friends and prove her innocence to the world.
