While most encryption is done these days on computers, there are still spies who do things the old way - numbered words in books, messages left in obscure languages, and the like. Robert "Code Buster" WITWICKY is a master of the more traditional aspects of spy-craft. A skilled comparative linguist, he knows several languages and has an encyclopedic knowledge of books and codes. Although a menace with real-world electronics and mechanical systems (he leaves that sort of thing to his brother), Code Buster is a master of both human and computer languages.
