The new season will see Keeley Hawes return to lead as Julie Green, the former assassin whose quiet life on an idyllic Greek island was derailed in season 1 when her estranged son Eddie (Freddie Highmore) arrived looking for answers around his paternity.
Tena has joined the cast as Inspector Cortez, “a sharp Spanish detective whose emotional intelligence and steely ambition should not be underestimated”.
The actress is best known for playing Nymphadora Tonks in the Harry Potter film series, as well as the wildling Osha in HBO series Game of Thrones.
Other new cast members in season 2 include Arnaud Binard (Emily in Paris) as Bastien, “a charismatic Frenchman whose path crosses with Julie” (below), and Boris Van Severen (Baptiste) as Titus, “a desperate and conflicted Belgian man driven by resentment and loss”.

Other new additions include Jacqueline Boatswain (Bridgerton), Monic Hendrickx (Penoza), Karl-El Santos (Stags), Mehdi Regragui (La Unidad Kabul), Casimiro Aguza (Sin Lìmites) and Tony Corvillo (Nowhere, Mano de Hierro).
The cast is rounded out by Amin Hamada (The Walking Dead: Daryl Dixon) and Lolo Herrero (Return to Las Sabinas).

Alongside Hawes and Highmore, other returning cast members from season 1 include Shalom Brune-Franklin and Devon Terrell.
Season 2 will pick up after Edward and Julie have returned from a disastrous trip to Northern Europe, where they find themselves estranged again following a fallout.

“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," the synopsis teases.
"When Edward’s honeymoon with Kayla (Shalom Brune-Franklin) 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?”
The Assassin is produced by Two Brothers Pictures, the company behind Fleabag, in association with All3Media International.
