The setting of this book is constant – a train. So one might think it’ll get boring! Nope. Trains are fast, they create blurred lines, and they are filled with strangers. We can say they add a suspense of their own! Amongst all the mystery books I have read in 2017, I had to go back to Poirot, at least once! The characters were wonderfully varied. The suspense was mysteriously kept. Loved the book. My favourite quote here was – “The impossible could not have happened, therefore the impossible must be possible in spite of appearances.”
