Ahead of "A Haunting in Venice," Check Out All of Agatha Christie's Mystery Books

The Colonel Race mysteries are Christie's smallest "collection," with just two novels focusing on him. The colonel is a character spun off from the Hercule Poirot mysteries, where he's introduced as a former army officer and a former leader of MI5. With his background in the spy world, he's usually seen to have an exceptionally open mind to any and all theories, which allows him to solve his cases quietly and efficiently. Along with his two "starring" novels, he also appears as a supporting character in the crossover "Cards on the Table" and in the famous Poirot story "Death on the Nile."
