"Heart-pounding mystery awaits the reader brave enough to crack Byrne's sinister cover. This series is everything... E. V. E. R. Y. T. H. I. N. G. BoB has a Ripper Street, Penny Dreadful, Frankenstein Chronicles vibe." — Whiskey & Wit Book Reviews

London, 1890. Blood and death are Fiona Mahoney's trade, and business, as they say, is booming.
Dying is the only thing people do with any regularity, and Fiona makes her indecorous living cleaning up after the corpses are carted away. Her childhood best friend, Mary, was the last known victim of Jack the Ripper. It's been two years since Fiona scrubbed Mary's blood from the floorboards, and London is no longer buzzing about the Ripper, but Fiona hasn't forgotten.
And she hasn't stopped searching for Jack.
When she's called to a murder in the middle of the night, Fiona finds a victim mutilated in an eerily similar fashion to those of the Ripper, and only a few doors down from Mary's old home. The relentless, overbearing, and irritatingly handsome Inspector Grayson Croft warns her away from the case. She might have listened, if she hadn't found a clue in the blood. A clue that will lead her down a path from which there is no return.As a killer cuts a devastating swath through London, a letter written in blood arrives at her door, and it is only then that Fiona realizes just how perilous her endeavor is. For she has drawn the attention of an obsessive evil, and is no longer the hunter, but the prey. Fiona Mahoney is in the business of blood.
But she's not the only one...

With intriguing twists, blood-chilling discoveries, and dazzling prose, USA Today Bestselling author Kerrigan Byrne proves a woman's work is never done, even when she is sleuthing out a serial killer.
