Elizabeth Bates must use everything she knows about the art of the con to stop a fellow scammer in his tracks in this first-ever thrilling crossover in the Victoria Thompson universe, featuring characters from her bestselling Gaslight Mysteries.

Famed former police detective turned private investigator Frank Malloy and his wife, Sarah, come to Gideon Bates desperate for legal guidance. The Malloys’ adopted daughter, Catherine, a burgeoning star of the stage, has announced her engagement to a man she barely knows. Catherine has recently gained access to her trust fund, and Sebastian Talbot appears very eager to marry her as quickly as possible.

As Gideon and his wife, Elizabeth, investigate, it becomes all the clearer that Talbot may not be who he says he is. As a former con artist herself, Elizabeth suspects one may be in their midst. Undeterred by her pregnancy, she must pull out all the stops to out swindle a swindler and save another woman from ruin.
