Review of 'The Mystery of the Blue Train (Poirot)' on 'Goodreads'
3 stars
The millionaire Rufus Van Aldin offers his daughter Ruth the famous ruby "Heart of Fire". Against her father's wishes, she decides to take the jewel with her on board of the "Blue train". During the trip, Ruth is thinking of ending her marriage and go back to her former lover. However, she is killed on the train and her jewels are stolen. Poirot is then hired by Van Aldin to find out who killed his daughter.
I enjoyed this story but I think it missed a bit of suspense. I liked that the character Katherine Grey was from St. Mary Mead (Miss Marple's town).
