After weeks of dead ends, police finally have a breakthrough in Muriel McKay's kidnapping case. A suspicious blue Volvo leads them to Rooks Farm in rural Hertfordshire. As they raid the property, they find mounting evidence implicating brothers Arthur and Nizamodeen Hosein. But there's still no sign of Muriel herself.

As detectives interrogate the brothers, a disturbing picture emerges of their backgrounds and possible motives. Meanwhile, the search of the sprawling farmland intensifies. Police are now certain they won't find Muriel alive, but can they find enough evidence to bring a murder charge without a body? The press descend on the scene, complicating the investigation. As the case builds, the question remains - what has happened to Muriel McKay?

Worse Than Murder - A tragic case of mistaken identity that shook Britain and launched a tabloid war.

One winter’s night in 1969, kidnappers targeting Rupert Murdoch’s wife abducted Muriel McKay by mistake. She was never seen again. Jane MacSorley investigates this shocking crime which baffled police and, more than 50 years on, remains unresolved.
