7. How was Ruth Kettering killed?
From Quiz The Mystery of the Blue Train
Answer:
Strangled
When the Blue Train arrives in Nice, Katherine is stopped from leaving. The Commissary of police - Monsieur Caux - tells her that there has been a murder. The lady who Katherine dined with - Ruth Kettering - has been strangled. Her maid was left behind, in Paris. The famous detective, Hercule Poirot, is also abroad the train and assists the Commissary. Katherine identifies the body - Ruth's face has also been disfigured. Ruth's jewel case has disappeared. The Commissary thinks a train robber killed Ruth. Lady Tamplin tries to persuade Katherine to write an eyewitness account of meeting Ruth, for a newspaper. There is a dinner party, where Katherine is introduced to Derek Kettering. He says that this is the third time they'd met - he passed her in the Savoy hotel and also in the travel agents. But Katherine corrects him - it is the fourth time. She saw him go into Ruth's compartment the night before - at least she thinks she did. Derek is given a note at dinner - the police want to see him. Van Aldin is surprised that Ruth left her maid, Mason, in Paris. Mason told Knighton that her mistress met a gentleman on the train, and then she told her to stay in Paris. Van Aldin gets word that his daughter is dead. Mr Goby informs Van Aldin that Mirelle, the dancer, and Derek Kettering were also on the Blue Train.
