Tunnel-master & Arsonist of the Great War (Kindle)
Sir John Norton-Griffiths was one of a breed of adventurer, pioneer, entrepreneur and soldier whose like is very seldom seen. From mining rich seams in South Africa he went on to lead the gallant miners who burrowed deep under enemy lines during the Great War. Always a controversial figure, he died in mysterious circumstances. This is the story of a true maverick, a formidable force and legend wherever he went.
