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, USAToday Bestselling author Kerrigan Byrne shows that a woman’s work is never done, even when she is sleuthing out a serial killer.

“Forgive me…for I have sinned.” And nothing interrupts a good confession like a murder. Fiona Mahoney stands in the ashes of her hopes facing her tempting adversary, Inspector Grayson Croft. Her sins are about to spill from her lips, when he says the one thing that could dispel all thoughts of revelation or redemption. Someone is leaving the corpses of prostitutes in the streets, and a name is being whispered in the fearful shadows. The name against which Fiona would sell her very soul for vengeance. Jack the Ripper. Old enemies and new friends join Fiona as she chases a relentless evil through the streets of Victorian London. She’ll pull upon every contact in her arsenal including Oscar Wilde, Arthur Conan Doyle, Inspector Aberline, “The Hammer” a charismatic gangster, “The Blade” an enigmatic assassin, and, of course, Jack.

Fiona Mahoney’s past returns to haunt her present as a prizefighter from her hometown becomes the only suspect in a gruesome, high-society murder. No one in London knows what befell Fiona’s family back in Ireland. At least, no one left alive. That is until her brother’s best mate arrives in the city for the bareknuckle bout of the century. Blood is spilled in the ring before the fight, and when Fiona is hired to clean it up, she finds that the boy from her past is now a dangerous man who may have answers she’d lost all hope of finding. But while she frantically tries to keep his neck from a noose, it becomes apparent that her own is at risk. Follow Fiona into her most chilling case yet, one that threatens to burn the precarious tightrope upon which she balances, and force her to decide, once and for all, on which side of the law she will choose to land.
