Marshal of Snowdonia Publisher's Summary

Living in Snowdonia was always retired detective Frank Marshal’s dream. Until a call for help turned it into his worst nightmare.

Retired detective Frank Marshal lives in a remote part of Snowdonia with his wife Rachel who is suffering from dementia. Working as a park ranger, Frank gets a phone call from close friend Annie, a retired judge. Her sister Meg has gone missing from a local caravan park and she needs his help to find her.

As Frank and Annie start to unravel the dark secrets of Meg’s life, it seems at first that her disappearance might be linked to her nephew and a drug deal gone wrong. In a shocking twist, their investigation leads them to a series of murders in North Wales from the 1990s and a possible miscarriage of justice.

Can Frank and Annie uncover the sinister truth so they find her sister in time to save her? Or will a brutal serial killer add Meg to his list of victims?

Marshal of Snowdonia is the first book in the Frank Marshal Crime Thriller series from multi-million bestselling author Simon McCleave. If you like dark thrillers, psychologically complex characters, and shocking twists, then you’ll love Simon McCleave’s pulse-pounding new novel. Perfect for fans of LJ Ross, JM Dalgleish, Rachel McLean, and JD Kirk.
