"The Mystery of Three Quarters" by Sophie Hannah

 An Hercule Poirot continuation novel. Poirot and faithful sidekick and narrator Inspector Edward Catchpool . A classic 'cozy' murder mystery involving a country house, the use of a great deal of psychology, well-hidden clues and a satisfying twist near the end.

But I was rather put off at the start when Poirot was satisfied that his taxi pulled up at the entrance of his apartment block such that "one could draw a straight line from the middle of the vehicle to the exact point where the doors met." (Ch 1; first paragraph). My problem is that, mathematically speaking, one can draw a straight line between any two points. I presume that Hannah means that the straight line would be perpendicular to the doors (and to the side of the cab)? I suspect that Poirot, being at least as pedantic as I am, would have corrected her himself.

Selected quotes:

  • "English discretion, Poirot had observed, had an outward appearance that suggested doubt." (Ch 1)
  • "What little hair he had hung in isolated strands of white, as if remnants of a wig he had once worn had adhered to his scalp." (Ch 16)
