The Darkroom of Damocles

The Darkroom of Damocles by Hermans, Willem Frederik. Paperback edition. ISBN: 9781590200810.

During the German occupation of Holland, tobacconist Henri Osewoudt is visited by a man named Dorbeck, who strangely proves to be Osewoudt’s spitting image in reverse. Dorbeck assigns Osewoudt to commit a series of dangerous assignments but things quickly go awry, with Osewoudt eventually killing his own wife. After the war, Osewoudt is taken for a traitor and captured. Osewoudt cannot prove that he received assignments from Dorbeck―he cannot even prove that his doppelganger ever existed.
