The chauffeur killed Lord Hazelton
This case can be solved from the facts discovered by Detective Percule Hoirot. The first fact to keep in mind is that:
- Lord Hazelton was killed by a blow on the head with a brass candlestick.
From this, it can be inferred that fact C. is not true because he did not die from a fatal dose of strychnine. In addition, it can be concluded that at the time of the murder in cook was not in the kitchen.
If the cook was not in the kitchen at the time of the murder, that means Sara was not in the dining room at the time of the murder (fact E). So it can be concluded that it was Lady Hazelton who was in the dining room.
If Lady Hazelton was in the dining room at the time of the murder, the one who killed Lord Hazelton was the chauffeur (Fact D)
According to the above, the one who killed Lord Hazelton was the chauffeur.
