Tension continues to build in the second instalment of Spy/Master as Mircea outs Victor to Nicolae and his wife Elena as the Soviet’s mole.

Now we’re getting Spy/Master, which comes to us from Romania. Sue Deeks, Head of BBC Programme Acquisition, says: “A classic spy drama set at the height of the Cold War, Spy/Master is an atmospheric, complex thriller, dripping with style and suspense.”

Alec Secăreanu, who is no stranger to British TV – he played organised-crime boss Darius Knezevic in Happy Valley and has also cropped up in Baptiste and the movie God’s Own Country – heads the cast as fictional character Victor Godeanu, who is a trusted advisor to Romanian President Nicolae Ceaușescu (Claudiu Bleont).

The dictator is becoming increasingly paranoid, but when the series begins he is unaware that he should be most wary of his right-hand man who, when he’s not dishing out advice, is also feeding information to the Soviets.

However, Victor fears that his double life is about to be exposed, and the drama plays out over one tense week as he tries to stay ahead of his own country’s spooks and the KGB.

In the first episode, Victor realises he is grave danger when he hears that his nemesis is gathering evidence against him. So, he decides to use a diplomatic mission to Germany as an opportunity to defect to the US, but his plan runs into trouble when his CIA contact, Frank Jackson (Parker Sawyers), gets stonewalled by his superiors. And even if Victor can start a new life in the US, will his wife and child be left to deal with the fallout at home? The tension continues to build in the second instalment as Mircea (Laurentiu Bãnescu) outs Victor to Nicolae and his wife, Elena (Elvira Deatcu), as the Soviet’s mole.

Victor’s old flame, undercover Stasi agent Ingrid Von Weizendorff (Svenja Jung), also seems dangerously close to figuring out what he’s up to. Meanwhile, Frank tries to sidestep the official channels to help him, but it could be too little, too late as Victor is summoned back to Bucharest.

If all this whets your appetite for more tales of Cold War era espionage, the good news is that the documentary series Secrets and Spies: The Nuclear Game begins on BBC2 on Wednesday, May 8.

It looks at the events of the summer of 1982, when the Cold War threatened to heat up, and an arms race brought the world to the brink of nuclear war.

The series features rarely heard archive interviews with KGB spy Oleg Gordievsky, as well as interviews with former aides to Margaret Thatcher and Ronald Reagan and MI5 and MI6 agents, some of whom have never spoke publicly before.
