Rouse

Rouse was a non-canonical character who was created for the film adaptation of The Mystery of the Spanish Chest in Series 3 of ITV's Agatha Christie's Poirot. He was a police sergeant seen helping Chief Inspector Japp in his office. Rouse is played by Edward Clayton. This character does not occur in the original story. Note, by coincidence, there is also a character named Edward Clayton in the episode.
