The Path of Duty charts the progress of a child of the Raj, Brigadier Geoffrey Herbert Bruno Beyts DSO, MBE MC known less formally as Bill or 'Billy'. During a career with the Indian Army he saw action against Burmese rebels, Waziri tribesman and the Japanese Army.

Bill Beyts and Ian Trenowden worked closely on this project together and sadly neither of them lived to see it come to fruition. It is produced precisely as told by Bill and written by Ian from typed notes.
