Martin Clemens was a civil servant on Guadalcanal, the main island in the Solomons group, as the Japanese  conquered Asia and prepared to roll into the South Pacific. Born in Scotland, he worked for the British colonial administration as a district officer.

When Japan seized the “impregnable” British fortress of Singapore, the other Brits fled in fear. 

Clemens, 25 years old, chose to stay until the Japanese surrender in 1945. He worked with local Solomon Islanders to send intelligence to the allies. When the Japanese started to arrive on Guadalcanal, he hid in the mountains and reported their every move.

He had no money or supplies, only his wits and wiles and the local people.
