Perfect for you if...

  • You love historical mysteries with romantic tension and genuinely clever protagonists who match wits as readily as they solve crimes.
  • You're drawn to stories where unconventional women operate in disguise, using their talents to navigate a world that won't let them exist openly.
  • You appreciate period detail grounded in real history: the actual science of the era, the art of caricature, the underground networks of Regency intellectuals.

Maybe not for you if...

  • You prefer cosy mysteries where the stakes are light and the violence happens offstage.
  • You want a straightforward whodunit where the solution emerges gradually without much character development alongside the plot.
  • You're looking for a romance where the love story is the primary arc; here it's secondary to the investigation and the characters' own ambitions.

About this book

In Regency London, the Earl of Wrexford, a brilliant but restless scientist, engages in a public clash of words with Reverend Josiah Holworthy after the clergyman publicly condemns him. London's most popular satirical cartoonist, A.J. Quill, mocks them both in print. When Holworthy is found murdered in a church—his face burned by chemicals and his throat slashed—Wrexford becomes the prime suspect. Charlotte Sloane, an artist herself, has secretly adopted the identity of her late husband to continue his work as A.J. Quill. When Wrexford discovers her secret, she fears exposure will destroy her. He proposes an alliance: she uses her sources to investigate Holworthy's involvement in questionable scientific practices while he works to identify the true killer. Together, they venture into London's hidden intellectual underworld to pursue a dangerous adversary before becoming victims themselves.
