In an alternate 1880s London, angels inhabit every public building, and vampires and werewolves walk the streets with human beings in a well-regulated truce. A fantastic utopia, except for a few things: Angels can Fall, and that Fall is like a nuclear bomb in both the physical and metaphysical worlds. And human beings remain human, with all their kindness and greed and passions and murderous intent. Jack the Ripper stalks the streets of this London too. But this London has an Angel. The Angel of the Crows.

From the moment Dr. J. Doyle takes lodgings in Baker Street with the Angel Crow, he becomes intimately acquainted with the supernatural and criminal worlds of London. But living with a rogue angel is not so easy; the pair find themselves drawn into mystery after mystery, from a man kidnapped by a vampire nest to Jack the Ripper's horrific murders. And besides Doyle's nightmares and shape-shifting, there is the lingering problem of Crow's sense of belonging and the worry that he might fall.

He is an unlikely person, despite his quickness, to be swept into the deadly contests of ambitious royals, assassins, and invading armies. But he is indeed drawn into all these things on a savagely cold night in his beloved city of Orane. And so Thierry must use all the intelligence and charm he can muster as power struggles merge with a decades-long war to bring his country to the brink of destruction.

Assigned to investigate is Ana Dolabra, a detective whose reputation for brilliance is matched only by her eccentricities. Rumor has it that she wears a blindfold at all times, and that she can solve impossible cases without even stepping outside the walls of her home.
