It was the fourth to feature an unnamed secret agent working for the British WOOC(P) intelligence agency. It follows "The IPCRESS File" (1962), "Horse Under Water" (1963), and "Funeral in Berlin" (1964). As in most of the author's novels, the plot of "Billion-Dollar Brain" (1967) is intricate, with many dead ends. The unnamed protagonist is ordered to Helsinki by Dawlish, his boss, to suppress a newspaper article, potentially embarrassing to the U.K. government, about to be published by a Finnish journalist. He finds the journalist murdered
The IPCRESS File Minister of Defence, thus making the novel itself the 'IPCRESS File' of the title. The events begin soon after his transfer from military intelligence to WOOC(P), a small civilian intelligence agency reporting directly to the British Cabinet, where he works under the command of a man named Dalby. An intelligence broker code-named "Jay" is suspected to be behind a series of kidnappings of highly placed and influential British VIPs with the intention of selling them to the Soviets, and the protagonist is assigned to meet with Jay to secure the release of "Raven", a high-ranking scientist and his latest target.
