Welcome to The Copse. A sleepy little cul-de-sac where nothing ever happens. Until . . . Sheila Craven, the widow at number 12, is found dead in her armchair. Smothered with one of her Liberty cushions. Detective Markham and the gang are on the case, following a twisty trail that leads straight to the high street - and Sheila's favourite Italian restaurant. But just when they think they've cracked the case, a second victim is found, floating in his own fishpond. Markham and his team realize they have a serial killer on their hands. And it's a race against time to stop them before more locals die.
