A harrowing new true crime series is set to grip the nation tonight as ITV premieres 'Killer in the House'. The first episode delves into one of the UK's most shocking recent murder cases, promising a heartbreaking and chilling watch for fans of the genre.
The Chilling Case of Nicholas Billingham
The series launches with the case of Nicholas Billingham, who was brutally murdered in 2021. In a devastating twist, his body remained undiscovered for months. The episode will detail how his partner, primary school teacher Fiona Beal, concealed his remains in the garden of their Northampton home while telling friends and family he had left her for another woman.
Beal's deception began to unravel when she was later found in a remote holiday lodge. Police, who initially did not suspect foul play, discovered suspicious journal entries that helped piece together the grim reality of what had happened. These writings were crucial in triggering a murder investigation that would expose a calculated and brutal crime.
