Hamilton Wrightson, millionaire mine owner and pastoralist, owns twenty three million acres of the best land in remote Western Australia. Yet all is not well in his wilderness empire. Slowly but surely, saboteurs are bleeding its enterprises to death: gangs of night raiders strike at its mines and homesteads, destroy and vanish without trace, leaving no clue as to their identity or motives. Wrightson hires George Galbraith, ex-diplomatic intelligence man and expert on subversion and terrorism to help unravel the mystery. It's Galbraith's first freelance job using his specialised talents developed in Asia and Africa. He has help from Wrightson's personal assistant, one of the most strikingly beautiful women he's ever seen - and the most unobtainable. Together they follow a trail of murder, arson and double-dealing through blistering heat to the terrorists' hideaway in the heart of a savagely hostile land.
