An abandoned, derelict neighborhood in Manchester, England is slated for demolition. Only a single, crumbling house is still inhabited, by a solitary man and hundreds of exotic finches. The eerie aviary sets the tone for the entire novel, a compelling police procedural centering upon an urgent search for a missing boy. DS Parker recruits a forensic psychologist to assist in what increasingly appears to be a serial killer case, and, as these two men form a grudging working partnership, author Martin takes readers within their minds as they struggle with the horrific details of the case. A haunting journey, surreal and malevolent, with richly developed characters compelling psychological underpinnings.
