Johnnie (Christmas Adventure)

In the short story Christmas Adventure, Johnnie was one of the young guests at the Christmas house party which Poirot attended. He addressed the hostess Miss Emily Endicott as "Aunt Emily", suggesting that he was Miss Endicott's nephew. He was one of three boys of school-going age at the party together with his cousin Eric and their friend Charlie Pease. In the expanded story The Adventure of the Christmas Pudding, Johnnie and Eric were combined into the character of Colin Lacey.
