The Fourth Protocol

Nobody thought the Soviets would dare break the Fourth Protocol... nobody but John Preston. July 1, 1968 - America, Britain and Russia sign a treaty to halt the spread of nuclear weapons and add four secret clauses or protocols. The most secret and dangerous was, and remains, The Fourth! Now someone is trying to breach the Fourth Protocol! They are smuggling a small nuclear device into Britain - piece by innocent looking piece! Spycatcher John Preston is working blind against an unknown deadline-but he must succeed.... © Fourth Protocol Distributors Ltd.
