Book 3
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.
Book 2
Mary’s second adventure as an undercover agent forces her to relive some harrowing childhood experiences as she seeks the identity of a murderer.

Mary Quinn’s new assignment sends her into the building site of the clock tower for the Houses of Parliament dressed as an impoverished young 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 second adventure offers a fictional window into the fascinating, if grimy, underbelly of Victorian London.
Book 1
Steeped in Victorian atmosphere and intrigue, this diverting mystery trails a feisty heroine as she takes on a precarious secret assignment.

Rescued from the gallows in 1850s London, orphan (and thief) Mary Quinn found herself at Miss Scrimshaw’s Academy for Girls, the cover for an all-female investigative unit called the Agency. Now seventeen, Mary must put her training to the test. Disguised as a lady’s companion, she infiltrates a merchant’s home in hopes of finding clues to the whereabouts of his missing cargo ships. But the household is full of deceptions, and there is no one to trust. . . . Or is there? Packed with suspense and evoking gritty Victorian backstreets, this breezy mystery marks the debut of a detective who lives by her wits while uncovering secrets — including those of her own past.
