Manhunt: The Night Stalker:

What does it take to catch a predator who has terrorised south-east England for over fifteen years? Delroy Grant – dubbed the Night Stalker – was one of the London's most feared and shocking sex predators. During his reign of terror, he established a clear MO. Visit a target at night. Remove a window pane and slide in. Unscrew the lightbulbs. Cut the power. Rip out the telephone wires. Tiptoe to the bedroom. Wake the victim by shining a light in their eyes. What followed was often unspeakable. When SIO Colin Sutton was drafted into the case, Grant had been at large for seventeen years. Stepping up where others had failed, he began the determined, relentless police work that had marked the end for infamous serial killer Levi Bellfield. Case by case, clue by clue. This is a chilling true story of one of the most testing manhunts the Metropolitan Police have ever undertaken. It is a glimpse into the heart of darkness – and into the mind and work of the brilliant detective who brought one of London's most feared monsters to justice.
