his uncle goodnight. The next day, Sir Reuben was found dead. Speaking with Trefusis, the somewhat meek man admits that during his nine years employment, he was ruthlessly bullied by Sir Reuben. Trefusis shows Poirot the scene of the crime and the detective is puzzled as to why there is a bloodstain on the writing desk but Sir Reuben's body was found on the floor. Poirot tries an experiment with his valet, George, and realises that Sir Reuben was clubbed as he sat in his chair and remained in position afterwards as the chair is low-down in comparison to the desk.

Poirot believes her and also realises that Leverson was drunk on the night in question and his strange manner is as a result of starting to shout at his uncle, pushing his shoulder and then realising he was dead as the body slid to the floor – hence the thud that Parsons heard. He is innocent as well as his uncle was killed earlier than when he was in the room. Poirot persuades Lady Astwell to partake in hypnosis to recall events of the night of the murder. She confirms what she has already told the police – that she argued with her husband in the Tower Room some ten minutes prior to Leverson coming back home. She also manages to recall
