Inspector Henry Cutter and Sergeant Gideon Bliss

London, 1893: High up in a house on a dark, snowy night, a lone seamstress stands by a window. So begins the swirling, serpentine world of Paraic O'Donnell's Victorian-inspired mystery, the story of a city cloaked in shadow but burning with questions: Why does the seamstress choose to jump out of that window? Why is there a cryptic message sewn into her skin? And how is she connected to a rash of missing girls, all of whom seem to have disappeared under similar circumstances?

It is the winter of 1893, and in London the snow is falling. It is falling as Gideon Bliss seeks shelter in a Soho church, where he finds Angie Tatton lying before the altar. His onetime love is at death's door, murmuring about brightness and black air and about those she calls the Spiriters. In the morning she is gone. The snow is falling as a seamstress climbs onto a ledge above Mayfair, a mysterious message stitched into her own skin.

Something is troubling Inspector Henry Cutter. Sergeant Gideon Bliss is accustomed to his ill-tempered outbursts, but lately the inspector has grown silent and withdrawn. Then, the murders begin. The first to die is the elderly Sir Aneurin Considine, a decorated but obscure civil servant who long ago retired to tend his orchids. If the motive for his killing is a mystery, the manner of his death is more bewildering still. The victims that follow suffer similar fates, their deaths gruesome but immaculately orchestrated.
