The series, based on the John le Carré book of the same name, stars Alexander Skarsgård, Florence Pugh and Michael Shannon and follows the manipulations of Martin Kurtz, an Israeli spymaster who intends to kill Khalil – a Palestinian terrorist who is bombing Jewish-related targets in Europe, particularly Germany – and Charlie, an English actress and double agent working on behalf of the Israelis.

Nick Taylor worked with composer Yeong-wook Jo to record his score at British Grove, returning to Air-Edel to mix. Andy Glen was the music editor and Matt Biffa was the music supervisor for the series, assisted by Ciara Elwis.
