Chilling True Crime Miniseries ‘In Plain Sight’ Captures Scotland’s Notorious Serial Killer Hunt

The gripping three-part miniseries In Plain Sight brings to life one of Scotland’s most infamous criminal cases: the relentless pursuit of serial killer Peter Manuel by dedicated detective William Muncie in 1950s Lanarkshire. Originally broadcast on ITV in December 2016, this atmospheric drama remains a standout in the true crime genre, blending historical accuracy with tense psychological cat-and-mouse gameplay. Now widely available on streaming platforms like BritBox and Prime Video, it continues to haunt viewers with its portrayal of evil lurking in everyday post-war Britain.

At the center is Douglas Henshall (Shetland), delivering a powerhouse performance as Detective Superintendent William Muncie, a no-nonsense Lanarkshire officer whose personal vendetta drives the investigation. Henshall portrays Muncie as a family man burdened by duty, living next door to the police station for quick response— a detail drawn from real life. His quiet determination contrasts sharply with the arrogance of Peter Manuel, played with chilling charisma by Martin Compston (Line of Duty). Compston’s Manuel is cocky and manipulative, taunting authorities while hiding in plain sight as the “Beast of Birkenshaw.”

The story spans over a decade, beginning in the mid-1940s when a teenage Manuel is first arrested by Muncie for housebreaking and sexual assaults. After serving time, Manuel emerges more dangerous, embarking on a killing spree from 1956 to 1958 that claimed at least eight lives, including women, teenagers, and an entire family. With limited forensic science—no DNA testing or modern profiling—the investigation relies on instinct, alibis, and persistence. Manuel’s brazen acts, like handing himself in with false alibis or even representing himself in court, heighten the tension.

Written by Nick Stevens and directed by John Strickland, the series excels in period detail: foggy streets, Brylcreem-slicked hair, and the social constraints of post-war Scotland. It avoids graphic violence, focusing instead on psychological depth and the human cost. Supporting performances shine, including Shauna Macdonald as Muncie’s supportive wife Agnes, and Gilly Gilchrist in key roles. The drama explores themes of justice, obsession, and the era’s unfamiliarity with serial killers—Manuel was among Britain’s early recognized ones.

Critics praised In Plain Sight upon release for its restraint and strong leads. Henshall’s nuanced portrayal earned acclaim, with reviewers noting his ability to convey Muncie’s moral steadfastness without melodrama. Compston, often cast as heroes, revels in villainy, making Manuel unnervingly relatable yet monstrous. The miniseries culminates in Manuel’s 1958 arrest, confession, and execution—the last hanging in Scotland before abolition.

Based on real events, Peter Manuel (born in the US to Scottish parents) terrorized Lanarkshire, murdering victims like 17-year-old Isabelle Cooke and the Smart family. Muncie, the only officer convinced of Manuel’s serial nature from early on, doggedly pursued him despite skepticism. The real Muncie consulted on the case until his death, and Henshall reportedly spoke with his daughter for authenticity.
