The Devil’s Claw by Lara Dearman

Jennifer Dorey thinks she is safe.
Following a traumatic incident in London, Jennifer has returned to her childhood home in Guernsey, taking a job as a reporter at the local newspaper.
After the discovery of a drowned woman on a beach, she uncovers a pattern of similar deaths that have taken place over the past fifty years.
Together with DCI Michael Gilbert, an officer on the verge of retirement, they follow a dark trail of island myths and folklore to ‘Fritz’, the illegitimate son of a Nazi soldier. His work, painstakingly executed, has so far gone undetected.
But with his identity about to be uncovered, the killer now has Jennifer in his sights.
And home is the last place she should be.
