In this special two-part conclusion to MISSING, Tim Weaver puts everything he’s learned to the test. He walks out the front door – not telling his family or his friends where he's going – and sees how long he can make it on the road and off the grid. With no phone, no computer, no contacts and under constant pressure of being found by a team of search experts, Tim has to deal with the practical and emotional challenges of life as one of the disappeared.

One year on, Tim Weaver returns to MISSING and discusses how the lessons he learned from the show’s guests influenced his new book, BROKEN HEART.

In the podcast's final episode, Tim returns to Quinn Norton and Frank M. Ahearn, both of whom have first-hand experience of watching people disappear. What exactly would people need to do in order to vanish? Is it a matter of determination, technical skill, deceit, or blind luck? What’s the balance between creating a new life and burying the old one? With their help, Tim sifts through the final evidence before asking, in the 21st century, is it really possible for someone to disappear?

Only 1% of people that go missing stay disappeared for longer than a year. Who continues looking for them, and how?

And how far would you go if a loved one went missing? Tim meets with noted clairvoyant Camilla Ventham Fraser, to explore the more unconventional paths a missing persons search can take.

Tim takes a unique, behind the scenes tour of the Crime Museum of Scotland Yard, accompanied by Jackie Keily, curator of the Museum of London.

What’s life like for someone that actually, successfully disappears? Is it glamorous, a heady cocktail of new identities and new experiences? Or is it a constant, grinding pressure, as you're isolated from your friends, family and - increasingly - the truth? This week, Tim is joined by journalist Quinn Norton, ‘digital hitman’ Frank M. Ahearn, and Dr Nigel Blackwood, as they describe the unique pressures of life on the run.

The UK has one CCTV camera for every 14 people – and that’s just the beginning. Fingerprinting and facial recognition technologies are now found on everyday items, including our phones. This week, Tim investigates how people manage to disappear in a world where we're being recorded in increasingly advanced ways, and is joined by Clive Reedman, a leading expert in biometrics, and Renate Samson, Chief Executive of Big Brother Watch. They discuss the possibilities – and repercussions – of trying to hide in a world where cameras know your face.

In a world of credit cards, online banking, mobile phones and social media, we’ve never been easier to trace and to follow.

They describe the infinite ways in which we all leave a data trail, and who is it that can – and will – follow it.

250,000 people disappear in the UK every year. 99% are found within the first year. But what about the remaining 1%? How are they still missing – and why did they disappear in the first place? This week, Tim Weaver meets with Dr Nigel Blackwood, forensic psychiatrist, and Frank M. Ahearn, author of 'How to Disappear’ - a professional that helps people vanish for a living. Using their expertise, Tim explores the complex reasons why people might choose to leave their life behind, and why that decisive step is even more difficult than you think.
