Reunited in the chaos of 1980s London, Sarah and Harry find danger and darkness lurking beneath the metropolitan veneer of wealth and technology. With trusty super-computer K9 and the brilliant Lavinia Smith alongside, new adventures are just beginning… 

Sadie Miller and Christopher Naylor return to the roles of the Fourth Doctor’s companions Sarah Jane Smith and Harry Sullivan – as originally played on TV by Elisabeth Sladen (Sadie’s mother) and Ian Marter – for their own brand-new series of full-cast audio adventures. 

A few years after leaving the TARDIS behind, journalist Sarah Jane takes an assignment that brings her back in touch with her old friend Harry, a doctor freelancing for UNIT. They soon team up on new investigations, and are joined by K9 (John Leeson) and Sarah’s Aunt Lavinia (Annette Badland, familiar to Doctor Who viewers as Blon Fel-Fotch Pasameer-Day Slitheen, taking over the role first portrayed in K9 & Company by Mary Wimbush). 

This team will discover that, though they’re no longer travelling the stars with the Doctor, there are plenty of threats to be uncovered and villains to be vanquished back at home on Earth.

Producer Mark Wright said: “I was so happy to take on producing duties for a trip back to the 1980s with Sarah Jane Smith and Harry Sullivan. These characters meant so much to me as a three-year old discovering Doctor Who for the very first time in 1974, so to be reuniting them for new adventures is a privilege – as is working with this incredible cast. 

“In Sadie Miller and Christopher Naylor, we have two actors who have grown together as Sarah and Harry, paying tribute to the memories of Sadie’s mum Elisabeth Sladen and Ian Marter with a great deal of love in their wonderful performances. With national treasure John Leeson joining the team as K9 and Annette Badland stepping into the shoes of Aunt Lavinia, something very magical happened in studio on our first day. 

“Our three stories for Reunited plunge Sarah and Harry into the dark corners of London’s metropolitan underworld. Extra-terrestrial artefacts are traded, technology is perverted, and sinister forces wait in the shadows of other dimensions…”
