A chilling new ITV documentary, Killer in the House: The Murder of Nicholas Billingham, uncovers the grisly truth behind one of Northamptonshire Police’s most shocking murder cases.
Teacher Turned Killer: The Shocking Murder of Nicholas Billingham
In 2021, primary school teacher Fiona Beal shocked her quiet Northampton community by stabbing her partner, builder Nicholas Billingham, in the neck. Furious after uncovering his affair, Beal didn’t stop there — she hid his body beneath thick layers of concrete in their garden.
Billingham, 42, vanished in November 2021. His partially mummified remains were only discovered months later, in March 2022, horrifying investigators.
Police Hunt: From Suspicious Injury to Gruesome Discovery
At first, cops didn’t suspect murder. That changed when officers found Beal wounded at a remote lodge in Cumbria. A hidden journal filled with dark secrets sent police racing back to their home on Moore Street.
Inside, investigators uncovered blood-stained bedding — and Billingham’s concealed corpse. Beal had tried to mask the crime by sending fake texts from his phone and lying to his employer, claiming they were isolating for COVID.
Justice Strikes: Fiona Beal Jailed for Life
In May 2024, Beal was locked up for life, with a minimum 20-year term. At sentencing, Billingham’s mother branded the killer “pure evil,” while a cousin said no punishment would ever feel enough.
Killer in the House: The Murder of Nicholas Billingham airs Thursday at 10.45pm on ITV. Catch all the drama and details later on ITVX.
