Sarah Gainham was born in London in 1915. She moved to Germany in her early thirties, shortly after WWII, and then to Austria, where she remained for over fifty years. It is in central Europe that her early thrillers such as Cold Dark Night, The Stone Roses and Silent Hostage are played out.

Night Falls on the City was first published to worldwide acclaim in 1967. She later wrote two further novels set in Vienna, A Place in the Country and Private Worlds. Gainham reported regularly on central European affairs for the Spectator, Encounter and the New Republic. She died in Austria in 1999.
