Margaret Haynes came to Berlin to disappear.

With borrowed papers, dwindling money, and a temporary apartment in Schöneberg, Margaret, David, and Luis are trying to build a life quiet enough to escape the unfinished consequences of Madrid.

Then Margaret meets Kurt, an elderly man in a neighborhood café who offers her work and appears to know exactly what she is capable of. By the following day, he is gone.

Kurt's granddaughter, Fawn, delivers a key and a warning. The key leads Margaret to documents and money hidden inside a cemetery mausoleum—and to a history powerful people believed had been buried.

Soon, two different groups are watching them. One is connected to Madrid. The other has been waiting years for Kurt's papers to surface. When Viktor Kostov returns, the four are forced out of Berlin and into a journey by train, back road, and borrowed shelter, pursued not for what they have done, but for what they now know.

INDIGO: The Ghosts of August in Berlin is a literary espionage novel about surveillance, loyalty, displacement, and the moment when running ceases to be survival and becomes surrender.

It continues the story begun in The Weight of Stone while standing on its own as a Margaret Haynes novel.
