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.
