A PR specialist refuses to market a car called a "Howard" - a colossal error that loses him a billion and makes him a national joke. He loses his hair, shaves his beard, takes a new name, and moves to Martha's Vineyard. Jump ten years: "Rolly" is a popular local whose sangfroid evaporates when the Howard's inventor moves to the island. Rolly, his old self unrecognizable, hatches a plan to rid the island of his nemesis; he also decides to woo the billionaire's wife. Fellatio, a former girlfriend, a woman who's lost weight, her boyfriend, the band Chicago, a menacing Chechen, a bus load of ill children, and a pair of ne'er-do-wells with experience with explosives figure in the story.

In 1979 Clive Sinclair, British inventor of the pocket calculator, frustrated by the lack of home investment in his project,the electric car, also opposes former assistant Chris Curry's belief that he can successfully market a micro-chip for a home computer. A parting of the ways sees Curry, in partnership with the Austrian Hermann Hauser and using whizz kid Cambridge students, set up his own, rival firm to Sinclair Radionics, Acorn. Acorn beat Sinclair to a lucrative contract supplying the BBC with machines for a computer series. From here on it is a battle for supremacy to gain the upper hand in the domestic market.
