When PI Evan Buckley’s mentor, Elwood Crow, asks a simple favor of him – to review a twenty-year-old autopsy report – there’s only one thing Evan can be sure simple is the one thing it won’t be. As he heads off to Cape Ann on the Massachusetts coast Evan soon finds himself on the trail of a female serial killer, and the more he digs, the more two questions align themselves. Why has the connection not been made before? And is Crow’s interest in finding the truth or in saving his own skin? It’s a difficult line Evan is forced to walk when the answers he finds threaten to drive a wedge between himself and Detective Kate Guillory as he struggles with his conscience and she with her duty, a grievous criminal act from their shared past only making things more difficult still, demanding compromise of them both. And as the case draws to a close and Evan unravels twenty years’ of duplicity and obfuscation, one simple mistake leads to unforeseen and disastrous consequences while at the same time teaching him a painful lesson too late – that even those you trust the most will let you down.
