agatha christie's poirot the mystery of the blue train

He is a very remarkable person.and has done some very remarkable things. THE MYSTERY OF THE BLUE TRAIN is set about ten years after World War 1, and Hercule Poirot has been 'retired from his profession for many years.' His former companion Captain Hastings does not appear in this story, although to a small extent he has been replaced by a valet George, whom Poirot uses at times as a sounding board. He sees Katherine Grey as a key witness, an excellent judge of character, and involves her in his investigation. Hercule Poirot is eventually engaged by Ruth Kettering's father to discover who murdered his daughter, and what became of the ruby necklace. She meets Ruth Kettering on the train, and then Hercule Poirot in Paris. The other element to the story is Katherine Grey, recently the beneficiary of an elderly woman's will, and on her way to Nice to stay with her relative Lady Tamplin. But what about the fact that her jewellery, in particular a necklace containing the fabulous ruby the size of a pigeon's egg known as The Heart of Fire, is missing, along with her maid? But what was the motive? The presence of her husband on the train makes him an immediate suspect especially as he becomes heir to her considerable personal fortune. By the time the train arrived in Nice she was dead. Ruth Kettering's journey to Nice on the luxurious Blue Train was her last. This version published by Harper Collins in 2001.
