Beyond the gilded ballrooms and salons of Regency London lurks a sinister web of intrigue and deception, and when a murder occurs within the scientific community, Lord Wrexford and Charlotte are the perfect pair to unravel it in USA Today bestselling author Andrea Penrose’s latest masterfully plotted mystery for readers of Charles Dodd, C.S. Harris, and Deanna Raybourn.

A welcome interlude of calm has descended on Wrexford and Charlotte, though with three lively young boys in their care and an unconventional circle of friends and allies, quiet rarely lasts long. And sure enough, in the dead of night, an old acquaintance appears and asks for help. His brother-in-law has been accused of murdering a fellow member of the prestigious Royal Society at their London headquarters, Somerset House. 

Wrexford agrees to investigate, and with a little unexpected help from their young charges, discovers that what seemed a simple case may be part of a darker, more dangerous plot, where science, money, and politics collide. A mysterious new technical innovation threatens to ignite a crisis throughout Europe, with frightening consequences for London’s financial world.

There is also personal upheaval for Wrexford and Charlotte, when a shocking secret from the past brings a profound change to their family, testing the bonds of loyalty and trust as never before . . .
