In a gripping blend of police procedural and psychological tension, 'Firewatching' unfolds with Detective Sergeant Adam Tyler at the helm of a cold case that warms up dangerously fast. A body, buried alive years ago, is found bricked up in a mansion's cellar. With the main suspect too close for comfort and Tyler's career hanging in the balance, he partners with an enterprising young constable to unravel a murky history. But in a town tight-lipped with secrets, and a menacing arsonist at large, every step could turn incendiary.
