Connections to Agatha Christie

 * In 1924 he wrote to Agatha Christie, expressing his admiration of her and her literary work. He also suggested some plot ideas. One idea involved a character named Genny, who takes over the role Captain Hastings usually have. In the end Genny turns out to be an unreliable narrator.
 * In 1959 he and his wife accompanied Queen Elizabeth II to a performance of the play The Unexpected Guest.
 * In 1969 he wrote to Agatha Christie, to congratulate on the 17th birthday of The Mousetrap. In her reply she acknowledged his previous letter (from 1924) and mentions that her brother-in-law had suggested a similar narrator/murderer plot idea. She also enclosed her latest book.
