Like the classic Doctor Who Quiz Books of the 1980s, The Lethbridge-Stewart Quiz Book features over 750 questions on the UNIT era of Doctor Who and beyond. For instance:
· In the television story The Time Monster what was TOMTIT?
· Who is attempting to penetrate the Earths crust in Inferno?
· What relation is James Lethbridge-Stewart to the Brigadier?
· What does UNIT stand for?
The Lethbridge-Stewart Quiz Book features questions from the Target, Virgin and BBC novels, the Big Finish and BBC audio stories, comic strips and the Candy Jar Lethbridge-Stewart novels.
