Murder on the Orient Express - Agatha Christie

Another aspect that I love about this book is that Dame Agatha totally messes with the reader. And yet, she cannot be accused of withholding information or clues that lead to the solution. 

‘Ma foi,’ said M. Bouc with violence. ‘But does everybody on this train tell lies?’

‘That,’ said Poirot, ‘is what we are about to find out.’
