The gripping documentary series returns this weekend with a hard-hitting double-bill to start the new series.
The two-part special, airing Sunday and Monday at 9pm, follows detectives from the Bedfordshire, Cambridgeshire and Hertfordshire Major Crime Unit as they investigate the disappearance — and tragic murder — of 74-year-old Stotfold landlady Annette Smith.
Detectives pieced together CCTV, forensics and digital evidence to uncover the truth in a case that rocked the community.
Senior officers say the show highlights both the complexity and compassion of modern policing.
Don’t miss part one this Sunday night at 9 on Channel 4.
