A third Victoria has ascended the throne of a steam-driven country where enormous clockwork giants walk the streets and airships carry news of the Ottoman threat in the East.
In the wake of a calamity that engulfed all of Europe, Inspector Vanessa Hargreaves of Scotland Yard is given the dubious task of policing steamcraft crime. Along with flamboyant detective Arturo C. Adler, she stumbles upon a conspiracy to use a horrific plague in an effort to prevent war.
But even as dastardly forces converge upon her, our high-heeled detective struggles with her devotion to Queen and Country, and the shadows under the Union Flag grow ever deeper.
Can she put a stop to this new disaster before her country is devoured by a Spectre of War?
