A thriller worthy of the name, from the days shortly before Ian Fleming got his typewriter out and everything began to get a just a little bit silly.
Steve Fraser is the reluctant hero of this short retelling in the first person of his horrific involvement in a coup (or counter-coup) in colonial SE Asia. He's a resourceful fellow, of perhaps better than average height, build, courage, intelligence, etc., but no superman. Fraser's an engineer, so has practical knowledge and skills, and he speaks the local language, which is always useful.
He finds himself (we find ourselves!), through a short series of wholly credible accidents and coincidences, caught up, with a woman, in a military revolution, just as he's on his way out of the country. It's a dreadful mess, in the way that such things must, in truth, be, and it's terrifying to watch it unfolding with all the inexorable inevitability of an uncontrollable natural disaster...
