Touching Evil

Touching Evil follows the intense and psychologically grueling cases of Detective Inspector Dave Creegan, an unorthodox investigator in the UK's Organized Crime Unit who returns to work after recovering from a brain tumor. The tumor changes his personality, leaving him with an obsessive, reckless, and boundary-pushing drive that gives him an uncanny ability to understand the minds of the depraved criminals he hunts. Alongside his cautious and by-the-book partner DI Susan Taylor, Creegan navigates the dark underbelly of London crime, pushing his own sanity to the absolute limit. The series is renowned for its gritty realism, dark atmospheric tension, and deep character exploration of trauma, morality, and the psychological toll of police work. It later inspired a short-lived American remake starring Jeffrey Donovan, but the original British television series remains a masterclass in psychological crime drama.
