For its loyal guests, Parkwood Holiday Village in west Dorset is a haven: woodland walks, a tranquil lake, service around the clock.
Until, just after midsummer, a body is found floating in the swimming pool.
Detective Nicola Bridge, exhausted by worries about her troubled teenage son, faces a resort full of suspects: a husband lying about his whereabouts, a high ropes instructor hiding unexplained scars, and a polished new manager with a dangerous secret.
With hundreds of guests and staff on site, Nicola must race to uncover a web of lies before the killer disappears.
Or strikes again...
