There's a very good reason to be afraid of the dark ...Alone on Dartmoor without a car, Erin O'Leary has gone to ground, hiding from Russian assassins. Her new neighbours are a disparate bunch: Gerald and Sylvia, whose social pretensions exceed their altered means; Ned and Lisa, newlyweds who only know each other from work and embittered Auriol, abandoned along with the dog. Crazy Betty, who lives in the woods, guards the land she considers her own. And a ghost is seen in the windswept churchyard tending her own grave. Winter approaches; the nights draw in. Each has a secret they want to hide. And when the killing starts, each has a motive.
