Ruin Beach (DI Ben Kitto #2) by Kate Rhodes

THE ISLAND OF TRESCO HOLDS A DARK SECRET 

Ben Kitto is the Scilly Isles' Deputy Chlof of Police, but as the sland's lazy summer takes hold, he finds himself misting the avaitement of the murder squad in London., When the body of professional diver Jude Trellon is discovered, anchored to the rocks of a nearby cave, his investigativé skills are needed 

At first it appears that the young woman's death was a tragic accident, but when evidence is found that suggests otherwise the islanders close ranks. With even those closest to the victim refusing to talk, it seems that plenty of people might have had reason to harm her 

Everyone is a suspect 

No one is safe.
