Mercenary

Rex Macare returns to New Zealand after several years on the front line of the Cold War in Germany, a pilot in the Royal Air Force. He is still young and restless and keen to make some real money. He puts the word around that he's a pilot for hire and it's not long before he finds himself deeply involved in the mercenary business, covert flying in Europe, Asia, and North Africa for serious money, but it's dangerous, very dangerous as he begins to realise as he is drawn inextricably into the big money high risk business. He meets and falls in love with the beautiful Kate, a fashion model and this introduces him to a wild sex scene.
The story is set around the world, the South Seas, Vietnam, Paris, Algeria, Australia, and the DDR, the German Democratic Republic, the old East Germany.
It's a fast moving story that I'm sure you will enjoy.
