Agent Anya Kingdom and Mark Seven take on the Daleks in The Worlds of Doctor Who – Space Security Service: Bret Vyon Lives!, a brand-new full-cast audio drama available now from Big Finish Productions. There’s also a family reunion (of sorts) in store for Anya as she encounters her uncle, Bret Vyon (Jon Culshaw), a man she knows is long dead. Bret Vyon first appeared in the 1965-66 TV serial The Daleks’ Master Plan, played by Nicholas Courtney. Their attempt to break her is by locking her in a cell with someone Anya knows is a fake: her beloved uncle Bret Vyon. The Worlds of Doctor Who – Space Security Service: Bret Vyon Lives!
