When Mary Quinn is ordered to work undercover after a petty thief steals from Buckingham Palace, she receives attention from a prince, wonders at a murder suspect's shared name with her father, and struggles with her feelings for James Easton.

Get steeped in suspense, romance, and high Victorian intrigue as Mary goes undercover at Buckingham Palace — and learns a startling secret at the Tower of London. Queen Victoria has a little problem: there’s a petty thief at work in Buckingham Palace. Charged with discretion, the Agency puts quickwitted Mary Quinn on the case, where she must pose as a domestic while fending off the attentions of a feckless Prince of Wales. But when the prince witnesses the murder of one of his friends in an opium den, the potential for scandal looms large. And Mary faces an even more unsettling possibility: the accused killer, a Chinese sailor imprisoned in the Tower of London, shares a name with her long-lost father. Meanwhile, engineer James Easton, Mary’s onetime paramour, is at work shoring up the sewers beneath the palace, where an unexpected tunnel seems to be very much in use. Can Mary and James trust each other (and put their simmering feelings aside) long enough to solve the mystery and protect the Royal Family? Hoist on your waders for Mary’s most personal case yet, where the stakes couldn’t be higher — and she has everything to lose.

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?

Rescued from the gallows in 1850s London, young orphan and thief Mary Quinn is offered a place at Miss Scrimshaw's Academy for Girls where she is trained to be part of an all-female investigative unit called The Agency and, at age seventeen, she infiltrates a rich merchant's home in hopes of tracing his missing cargo ships.
