DI Zoe Finch has enough on her plate as the trial of her deadliest enemy gets underway. But when a birdwatcher stumbles across a body in the shifting flatlands of the Solway coast, the evidence takes her team in some disturbing directions. Has the victim fallen foul of the same organised criminals Zoe has spent the last two years trying to put behind bars? Or could there be a connection with the disappearance of a man from a local caravan park years earlier? With shocking developments in court, unpredictable politics in the police and her relationship with DI Carl Whaley in uncertain territory, Zoe finds herself facing some of her biggest challenges yet, both personal and professional.
