The second series picks up after Edward and Julie have returned from a disastrous trip to Northern Europe, where they find themselves estranged once again following a mysterious fall-out no one is willing to discuss.

Julie's days as an assassin are far from behind her as she has slipped back to her old ways, whilst navigating something just as perilous… the dating scene. When Edward's honeymoon doesn't go quite as planned, he must reunite with Julie to take on Spain's corrupt underworld, but can they survive the job and mend the rift that tore them apart?

Keeley Hawes said: "I can't wait to step back into Julie's world. To reunite with Freddie and our extraordinary cast, and to dive deeper into Julie's life and her complicated relationship with Edward, is a privilege. There is so much more to uncover, and audiences are in for a treat."

Freddie Highmore said: "What fun it'll be to get the gang back together – I can't wait to be reunited with so many of the cast and crew. Harry and Jack have cooked up another spectacular adventure, and I feel so lucky to have the brilliant Keeley as a sparring partner once again."

Daisy Mount and Alex Mercer, executive producers for Two Brothers, add: "Reuniting with Keeley, Freddie, Shalom and Devon is a real privilege as we dive back into the world of The Assassin – of course we couldn't leave them sailing off into the sunset in blissful harmony. The second season is full of twists, turns and thrilling unpredictability – just like the characters at the centre of it."

All3Media International's Maartje Horchner, EVP content, notes: "We're delighted that this fabulously stylish and witty thriller, so well received globally, is returning. The cast really made the characters their own – and Jack and Harry's second series takes them on a hugely engaging journey that we know audiences will find entertaining."
