The series will see Tchéky Karyo (The Missing) reprise his role as the retired police investigator Julian Baptiste. Karyo will be joined by Fiona Shaw (Killing Eve), who will play a British Ambassador whose entire family goes missing during a skiing holiday in the Hungarian mountains.

As the case descends into something far more brutal and dangerous, Baptiste must navigate the secretive and corrupt underworld of Budapest and the unrelenting media to solve this high-profile international case.

Written by Harry and Jack Williams, Baptiste will see its damaged protagonist attempt to solve this case while enduring the grief of a horrific personal tragedy. The series has been produced by the writers’ production company Two Brothers Pictures; the team behind Fleabag and The Missing.

Fiona Shaw commented: “I’m honoured to be joining this hugely talented and committed team with the superb writing of Harry and Jack Williams and under the direction of Thomas Napper.

“I’m so lucky to be working with all the best of the new generation!”

Filming for Baptiste’s second series will commence in February.
