With a superb track record, including the Line Of Duty series, Jed Mercurio steps the controls up to eleven. An intriguing conspiracy thriller with red herrings and twists and turns galore. With no titles, the first episode goes straight into the action with an edge-of-the-seat thrill ride on a train. As you try to get your breath back during episode two there are even more surprises that will leave you reeling. Richard Madden and Keely Hawes are superb, as is the rest of the cast. A big hand for the young lady in episode one whose acting contributed greatly to the tension. The BBC shows once again that it can really produce the goods.
