Two murders. A one-way ticket to trouble.

And it's up to Kate to derail the killer.

London, 1929. In the darkness before dawn, a railway porter, unloading a special train from Yorkshire, discovers a man's body, shot and placed in a sack. There are no means of identification to be found and as Scotland Yard hits a dead end, they call on the inimitable Kate Shackleton, a local sleuth, confident her local knowledge and investigative skills will produce results. But it's no easy task.

Suspicion of political intrigue and fears of unrest in the Yorkshire coalfields, impose secrecy on her already difficult task. The murder of a shopkeeper, around the same time, seems too much of a coincidence. The convicted felon was found with blood on his hands, but it's too tidy and Kate becomes convinced the police have the wrong man.

By then it's too late. Kate finds herself in a den of vipers. The real killer is still at large, and having tinkered with Kate's car, nearly causes her to crash. Not only that, but Scotland Yard has turned their back on her. As Kate edges toward the shocking truth, she's going to need all the strength and resourcefulness she can muster to uncover this sinister web of deceit.
