Spoiler:

Georgia Fenchurch appears to be an unassuming antiquarian bookseller in Victorian London, but the life she leads is as exciting as any adventure novel. For Georgia is a member of the Archivist Society, a secret association of private investigators led by the mysterious Sir Broderick.

When a frantic woman comes to Georgia claiming that her neighbor, Nicholas Drake, has been abducted by the notorious Duke of Blackford, Georgia and the Archivist Society agree to take the case. But Drake is no innocent—he is a thief who has been blackmailing many of the leading members of London society. To find Drake and discover who is behind his abduction, Georgia and her beautiful assistant, Emma, will have to leave the cozy confines of their bookshop and infiltrate the inner circles of the upper crust—with the help of the dashing but dubious Duke of Blackford himself.

But the missing thief and his abductor are not the only ones to elude Georgia Fenchurch. When she spies the man who killed her parents years ago, she vows to bring him to justice once and for all…at any cost.

The second in the series, The Counterfeit Lady, is also on "sale" for $5.99, which is a lot for a sale price on a 2014 title, but it seems to be more regularly $11.99, so I guess $5.99 is a sale compared to that...

The new mystery set in Victorian England from the author of The Vanishing Thief...

Who would suspect antiquarian bookseller Georgia Fenchurch of leading a double life—as a private investigator for the clandestine Archivist Society in Victorian London? When England’s national security is compromised, Georgia must pose as a titled lady to root out a spy…

A cousin of Georgia’s dear friend, Lady Phyllida Monthalf, is brutally murdered in her home during the theft of blueprints of a new battleship designed by her husband—who now stands accused of her murder…and treason. The Duke of Blackford, in service to Whitehall, enlists Georgia and the Archivist Society to assist in the investigation. Playing the part of the duke’s new paramour, Georgia gains entry into the upper echelons of London’s elite, where amidst elegant dinners and elaborate parties a master spy schemes to lay hands on the stolen plans.

The duke is no stranger to the world of international espionage, but Georgia is out of her element in more ways than one. She must not allow her genuine attraction to the duke—or her obsession with finding her parents’ killer—to distract her from her role. But when a mysterious stranger threatens to expose her, the counterfeit lady may be in real trouble…
