Levi Bellfield was the first British prisoner to be sentenced to not one, but two whole life orders. He murdered three women, including the schoolgirl Milly Dowler, and was also convicted of multiple rapes and another attempted murder. In this episode, Andy & Neil speak to Neil Lancaster, one of the detectives who was a key part of the surveillance team which led to Bellfield's arrest, and hear what it was like to tail this monster for days on end.

Neil Lancaster explains how he felt watching such an evil character up close - and how the killer very nearly escaped police's clutches as the surveillance operation reached a dramatic conclusion.

Neil L spent decades as a detective working on cases such as Levi Bellfield's, but he's now one of the country's most popular & successful crime writers. He tells Andy and Neil how he's used his real-life experience to create memorable characters and gripping plots - and gives Neil Basu a few tips along the way as well!
