Martin Walker’s standalone fiction predates his Bruno series by decades. The Infiltrator (1978), The Money Soldiers (1980), and A Mercenary Calling (1980) are thrillers written during his years as a Cold War journalist, drawing on the geopolitical tensions he covered professionally.
The Caves of Perigord (2002) is a historical novel that anticipates the Bruno series by setting its story in southwestern France. The book connects prehistoric cave paintings in the Dordogne to events during World War II, layering multiple timelines together. It serves as an early sign of Walker’s deep attachment to the French region that would become Bruno’s home.
