Driscoll Rose and his two brothers own and run The Rose Room, a well-known and profitable gaming club in London. Unknown to those who visit and spend their money there, the brothers also work for the Crown in positions only known to a mysterious man at the Home Office.
Miss Amelia Pence is on the run from her step-brother who has nefarious plans for her. Late one rainy night she crawls into Driscoll’s office window and falls at his feet. Intrigued by the woman, he offers her a job as the only female dealer in the Rose Room.
Much to Driscoll's frustration, Amelia is secretive about who she is, and where she lives since she can trust no one. The growing attraction between them and his desire for her is causing him to dismiss the fact that crowds of gamblers swarm her table each evening, but the profits she turns in are not what they should be.
Can Driscoll convince Amelia to trust him with her secrets or will he discover a deception that contradicts everything he believes about her in his heart? Just when he decides to confront her, she disappears. . .
