West Berlin, 1979. Helen Abell oversees the CIA's network of safe houses, rare havens for field agents and case officers amidst the dangerous milieu of a city in the grips of the Cold War. Helen's world is upended when, during her routine inspection of an agency property, she overhears a meeting between two unfamiliar people speaking a coded language that hints at shadowy realities far beyond her comprehension.
Before the day is out, she witnesses a second unauthorized encounter, one that will place her in the sight lines of the most ruthless and powerful man at the agency. Her attempts to expose the dark truths about what she has witnessed will bring about repercussions that reach across decades and continents into the present day, when, in a farm town in Maryland, a young man is arrested for the double murder of his parents, and his sister takes it upon herself to find out why he did it.
