A series of gruesome murders, each more bizarre than the last, plunges London into a state of terror. Arthur Bryant and John May, detectives of the Peculiar Crimes Unit, are tasked with solving these increasingly outlandish crimes. They must navigate a city steeped in history and shadowed by dark secrets, facing opposition from both the criminals and their own superiors.

The Bryant & May series is known for its blend of classic detective work with a distinctly British, often eccentric, sensibility. "The Bleeding Heart" continues this tradition, offering a complex mystery set against the backdrop of London. Readers often praise Fowler's intricate plotting and the engaging character dynamics between the two lead detectives. The novel is expected to deliver a satisfyingly intricate puzzle with a strong sense of place.
