A murdered prison guard, a dangerous fugitive, and missing evidence all point to one thing-the shadows of corruption are brewing within Scotland Yard... Inspector Henry Field is under pressure to track down an escaped prisoner-a man suspected of murder in a cold case that Henry is desperate to put behind him. When a prison guard turns up dead, it seems obvious the fugitive is to blame. But as Henry delves deeper, the evidence twists into something far more sinister, leading him to a chilling realization: the true threat is lurking closer than he ever imagined. Amelia Greystone never intended to become entangled in yet another murder investigation, but danger finds her once again. And the suspect is the very same man accused of killing her husband-someone who clearly wants her silenced. As deception tightens its grip and danger closes in, Henry and Amelia must navigate a treacherous web of lies. Can they unmask the killer and expose the corruption before one of them becomes the next victim? This fourth novel in The Field & Greystone series set on the dark streets of Victorian London is perfect for fans of Irina Shapiro, Andrea Penrose, and Charles Finch.
