River Song (Alex Kingston) travels between eras – ranging from 1936 to 2014 – while trapped in a house full of mysteries and heartbreak in a four-part domestic drama, written by Tim Foley.

Alex Kingston said: “There are lots of secrets within the bones of this house that River is trying to unearth and solve like a jigsaw puzzle. This story is about opportunities missed, love thwarted and people unable to be honest and open about who they really are. It’s a very bittersweet telling of a story – there's tragedy within.”

The stellar cast also includes Jemima Rooper (as Mary Mortimer), Isla Blair (as Older Mary Mortimer), Jack Holden (as Harry Mortimer), Timothy Bentinck (as Older Henry Mortimer), Wendy Craig CBE (as Older Maddie Mortimer), Mark Elstob (as Hugo) Vineeta Rishi (as Carla Alcazar), Ronak Patani (as Vinay Siddiqui), and Phyllida Nash (as Cook).

The Worlds of Doctor Who – The Diary of River Song: Friend of the Family is now available to own for just £24.99 (collector’s edition CD box set + download) or £19.99 (download only).

This emotional story is told across four, hour-long episodes...

River Song decides to investigate a temporal anomaly after a Luna University expedition makes some odd discoveries in an old Earth house - pages of her own diary with an inscrutable riddle written across them.

However, her investigation goes badly wrong when she is transported back into the past of the house and gets trapped within its grounds.

The house is the home of the Mortimers and with a limited ability to travel back and forth in time across eighty years and multiple generations she finds herself witnessing key moments in their family history.

If she wants to escape, the words in her diary are not the only riddle she has to solve. But not everyone in the house will survive what’s coming. And not everyone is on her side.

Writer Tim Foley added: “It’s discussed that big houses can either tell love stories or ghost stories and I knew that for an audio like this, I wanted to tell both. A house is such a personal thing and they have so many stories to tell. Not only is this about the Mortimers, but it’s about the house as well and at the heart of this story, is River Song.”
