Harry Clarke

Harry Clarke was a non-canonical character who was created for the film adaptation of Four and Twenty Blackbirds in Season 1 of ITV's Agatha Christie's Poirot. Harry was the assistant of George Lorrimer, who, in the film, was the manager of the Carlton Theatre, Bethnal Green. When Poirot and Hastings went to the theatre to look for Lorrimer, Harry told them that he had gone to the funeral of Anthony Gascoigne in Brighton.

Harry Clarke was played in the film by Geoffrey Larder. This character does not occur in the original story.
