When a crucial mission collapses in the USA and Eva finds herself in terrible, fatal jeopardy she knows she has no option but to run and hide – forever.
Once a spy always a spy. No-one can be trusted. But now Sally Gilmartin yearns to end her years of restless watching and waiting. Thirty years on, the only man who can bring this about is her former lover and spymaster, Lucas Romer, now Baron Mansfield of Hampton Cleeve (Michael Gambon), and the only person she can call on for help is her daughter, Ruth.
The final chapter of this epic story of love, duplicity and betrayal is about to end – and who will pay the greatest price remains to be discovered.
Hayley Atwell plays Eva Delectorskaya and Rufus Sewell plays the younger Lucas Romer while Michael Gambon plays the older Lucas Romer. Michelle Dockery plays Ruth Gilmartin and Charlotte Rampling plays her mother Sally Gilmartin.
