Who killed Lady Van der Sluty and Why? It was Mrs. Kettle, the cook, who did it by adding clam juice to Van der Sluty’s drink.
Why? Mrs. Kettle was good friends with Mildred, a servant at Downturn Abbey. Mildred had an affair with John the footman and became pregnant. Later, Lady Van der Sluty became interested in the good-looking footman and also had an affair with him. Feeling abandoned in her condition, Mildred decided to kill herself.
Blaming Van der Sluty for Mildred’s death, Kettle decided to take revenge on her last night at Downturn Abbey.
When she confessed to the guests that she had murdered Van der Sluty, she admitted she “enjoyed watching her die.”
