This is one of the most unrealistic tv series I’ve ever encountered. A Danish agent who turns up in Britain and immediately gains access to senior level British intelligence officials. A down-and-out ner do well who gains unobstructed access to the British PM, kills two security agents and fails to kill the PM only because the daughter of the head of British intelligence (yes, she works for her father) kills him. Utter nonsense. Three episodes; that’s all I can take. Rubbish.
