A fascinating spy vs. spy story in which a couple of European directors of intelligence decide to pay for their retirement by purchasing a newsletter called Intercom and making it publish little intelligence tidbits that none of the intelligence services wanted to see disseminated. The story takes place during the Cold War, with operatives from the CIA and KGB involved in trying to discover the source of all the embarrassing leaks. The story of The Intercom Conspiracy is told from a multiplicity of viewpoints, but ultimately it is the editor of the newsletter, a Canadian named Theodore Carter based in Switzerland, who comes to the fore. Ambler tells his tale with a great deal of tongue-in-cheek humor, which makes it rather fun to read.It reminds me of something that Alfred Hitchcock once said about the perfect mystery being one in which not only the bad guys but the police are after the hero.
