A riproaringly ludicrous adventure novel with a climax conceived in supercolossal-gigantiscope. IRA Commander Quinn runs a secret brothel on Coultry Bay, but this is only a mask for the Big Scheme--the sabotaging of Britain by the release of 1.2 million barrels of crude oil into the North Sea from a British Petroleum oil field offshore of Holland. Quinn hijacks the greatest supertanker ever built, the American Enterprise, and, with a handful of hand-picked rebels, plans to ram this oil-filled Godzilla into Mavis A.--a city-sized offshore oil-drilling structure. This collision should no doubt cause the kind of havoc usually reserved for Japanese monster movies, but the Platform Master of Mavis A. is 40-year-old Noel Cullenbine, a former mechanical child prodigy (""a Mozart of science"") and six-foot-two of white-knuckled John Wayne. Can Cullenbine forestall the oil-flood, despite Quinn's fail-safe demolition devices and a North Sea typhoon? The outcome is almost worth waiting for, but would look a lot better on the screen than on the page.
