Dunn's Conundrum

It’s the mid-1980s and the cold war hasn’t thawed. The Library, a super-secret U.S. espionage agency is keeping an eye on the Russians and everybody else. A dozen elite intelligence experts relentlessly sift out classified information from everywhere. They know all the secrets except for one – which of the librarians is a traitor.

It’s up to Walt Coolidge, a librarian with a Sherlockian gift for analyzing people’s garbage, to uncover the mole and, if he fails, it could lead to nuclear Armageddon.
