Murder on an abandoned housing development--and a web of dark secrets stretching back decades... Looking for clues about her sister's death amid the crumbling decay of a derelict and near-deserted London neighbourhood, urban explorer Connie Darke makes a terrifying discovery: William Stark, the estate's architect and long-time resident, is hanging from the church's vaulted ceiling. For DI Lew Kirby, there's no doubt that Stark was lured to his death--but who wanted him dead, and why? As Connie begins a covert investigation, desperate to find a connection to her sister, Kirby soon discovers that the remaining residents have something to hide. Could there be a connection between Stark's death and the unsolved case of Kevin Shires, a boy who went missing from the estate decades ago? And with Kirby and Connie both digging into the long-buried history of the estate's darkest corners, what other secrets will be unearthed from the ruins of Grasmere?
