July, 1847. Now a happily married mother-of-two, Liberty Lane is undertaking very few private investigative assignments. But when she is kidnapped from outside a smart London townhouse, where she had been attending a dinner party with her husband Robert, she must call on all her old investigative skills to discover who has taken her, and why.

As Libby tries to formulate a plan of escape, her old friends, former street urchin Tabby and groom Amos Legge, desperately search for her. Convinced that somebody in the Maynard household, where the dinner party was held, knows something about Libby's disappearance, Tabby keeps watch on the house - and makes a truly shocking discovery.
