The Assassin is a new Prime Video thriller starring Keeley Hawes.

The six-parter sees Keeley play a retired contract killer, whose solitary life on an idyllic island is interrupted when her son arrives. It boasts a great cast, here's our who's who guide to all the key characters...

"Julie's happy living on her own, when suddenly Edward comes back into her life. They are not completely estranged, as there have been a few texts over the years," says Keeley.

She adds: "Julie is not the coolest assassin in the world, but she’s a great character! She and Edward are actually very similar, although they would never admit it."

EDWARD (FREDDIE HIGHMORE)

The investigative journalist wants to know the truth about his father. Freddie says: "Edward arrives on the island attempting to reconnect with his mother and with questions about his past, their relationship and who his father is. Edward is harbouring a lot of secrets and feelings, so this is a big step for him."
