Tune in to BBC Radio 4 today at 4:30pm UK time to listen to the first episode of the new series of the award-winning Digital Human! You can expect some incredible stories, plus some extended content online – including specially commissioned art from our resident illustrator.

It’s been a remarkable fortnight reliving the best of our more than 40 episodes every night on BBC Radio 4; props to our producer Vic for landing a Pick of the Week from Isy Suttie for the atmospheric and eerie celebration of Abandon.

Vic is the first producer up this series, with more thoughtful stories about what makes us human in the 21st century. Listen in at 4:30pm UK time (and on iPlayer after) to find out how online detectives track down the true identities of missing and found persons, when traditional detection methods have failed.

This is crowdsourcing at its most urgent.

We’re on every week at the same time, so tune in! And don’t forget to check out our jam-packed Tumblr for the background check, and exclusive goodies.
