Fans of vintage international game show Jeux Sans Frontières have a treat in store as Endeavour and the gang go to watch Fancy take part.

But when Fancy hurts his ankle, who will he call on to take his place?

The fun ends suddenly when one of the German team is shot dead, shortly followed by Special Branch shutting down the investigation.

However, Endeavour, being Endeavour (we wouldn’t have him any other way!), ploughs on regardless and uncovers some murky dealings connected to the Cold War and espionage.

Fred, meanwhile, is mulling over his future but is distracted by an apparent case of domestic abuse involving his local tobacconist.

But as the situation takes a surprising turn, will justice be served?
