The Sailor Who Fell From Grace With the Sea (Unabridged‪)‬

A band of savage 13-year-old boys reject the adult world as illusory, hypocritical, and sentimental, and train themselves in a brutal callousness they call 'objectivity'. When the mother of one of them begins an affair with a ship's officer, he and his friends idealise the man at first; but it is not long before they conclude that he is in fact soft and romantic. They regard this disallusionment as an act of betrayal on his part - and the retribution is deliberate and horrifying.
