1952. Soviet troops control British streets.

After the disastrous failure of D-Day, Britain is occupied by Nazi Germany, and only rescued by Russian soldiers arriving from the east and Americans from the west. The two superpowers divide the nation between them, a wall running through London like a scar.

When Jane Cawson calls into her husband's medical practice and detects the perfume worn by his former wife, Lorelei, star of propaganda films for the new Marxist regime, she fears what is between them. But when Jane rushes to confront them, she finds herself instead caught up in the glamorous actress's death.

Nick is soon arrested for murder. Desperate to clear his name, Jane must risk the attention of the brutal secret police as she follows a trail of corruption right to the highest levels of the state.

And she might find she never really knew her husband at all.
