Squares of the City [EPUB ebook] 

Ciudad de Vados was the pride of Latin America – a gleaming city of the future where only ten years before there had been barren rock and wasteland. But Vados had problems. When Boyd Hakluyt was called in, his brief seemed simple: reroute the traffic to drive out the shanty towns that disfigured the city. It was an easy job – until Hakluyt found himself unwillingly involved in a web of deadly political rivalries. Then came the first murder . . . Hakluyt started getting answers to questions he hadn’t asked. Too many people got too interested in him. And the pattern that started emerging was sinister, terrifying – and almost unbelievable . . .First published in 1965.
