What’s Your Agatha Christie I.Q?, originally published in 1996 by Citadel Press, has been updated and is being reissued by LL-Publications. The new title is The Agatha Christie Triviography and Quiz Book. If you enjoy mystery trivia, check out my other two mystery-trivia books The Sherlock Holmes Triviography and Quiz Book and The Alfred Hitchcock Triviography and Quiz Book, also updated and just out.
