A follow-up to A Spy in the House finds mid-19th-century orphan Mary Quinn tackling a latest case in which her efforts to discover a murderer's identity force her to relive harrowing childhood experiences.

In a tale steeped in action, romance, and the gaslit intrigue of Victorian London, Mary Quinn’s detective skills are pitted against a cunning and desperate opponent. Mary Quinn has a lot on her mind. James Easton, her longtime love interest, wants to marry her; but despite her feelings, independent-minded Mary hesitates. Meanwhile, the Agency has asked Mary to take on a dangerous case: convicted fraudster Henry Thorold is dying in prison, and Mary must watch for the return of his estranged wife, an accomplished criminal herself who has a potentially deadly grudge against James. Finally, a Chinese prizefighter has arrived in town, and Mary can’t shake a feeling that he is somehow familiar. With the stakes higher than ever, can Mary balance family secrets, conflicting loyalties, and professional expertise to bring a criminal to justice and find her own happiness?

Mary’s second adventure as an undercover agent forces her to relive some harrowing childhood experiences as she seeks the identity of a murderer. (Ages 12 and up) Mary Quinn is back, now a trusted member of the Agency, the allfemale detective unit operating out of Miss Scrimshaw’s Academy for Girls. Her new assignment sends her into the grimy underbelly of Victorian London dressed as a poor boy, evoking her own childhood memories of fear, hunger, and constant want. As she insinuates herself into the confidence of several persons of interest, she encounters others in desperate situations and struggles to make a difference without exposing --or losing --her identity. Mary’s adventure, which takes place on the building site of the clock tower of the Houses of Parliament, offers a fictional window into a fascinating historical time and place.
