His only novel not playing the far east. This tells the story of a small helicopter outfit, supplying the iranian oil rigs with everything needed. The company belongs to Struan's Noble House, too, the boss is Andrew Gavallan, Ian Dunross' nephew. It depicts the events just before and during the revolution, toppling the Shah, and about all the trouble that came for S-G Helicopters due to the fightings between the different iranian factions (muslim fanatics, soviet-led communist rebels and local tribes) and between all of them and any non-iranian person. There's romance, too, thanks to two threads, one about a finnish pilot of S-G Helicopters and his iranian wife, trying to escape via Turkey, and the other one with another pilot who has also an iranian wife. This is also a very good book by Clavell, full of action, adventure, suspense, romance and exotic places and people.
