A delicate mission takes retired nurse and part-time spy Evelyn Chambers to Lisbon, where she must earn the trust of a dying woman who once risked everything for the West and was abandoned for it.

Sigrid Fehrmann was a Cold War asset who fed secrets from inside the East German embassy for years. When her handler vanished and left her exposed, she disappeared into the city and never looked back. Now, decades later, she’s reaching out with something that people would kill to keep hidden. But she’s fading fast, and she’ll only speak to a woman.

Evelyn isn’t there to interrogate or debrief. She’s there to listen, to sit with a woman at the end of her life and draw out a story that has been locked away. It will take patience, presence, and a kind of trust that can’t be rushed. Whatever Sigrid knows has stayed buried this long for a reason, and Evelyn may not be the only one who wants to hear it.

Because some secrets don’t stay quiet just because the Cold War ended.
