Appointment with Death

I listened to the BBC dramatisation version of this audio book and thoroughly enjoyed the voice acting. The story and the murder was set mostly in Petra, somewhere I truly wish to visit but even if I wasn't aware of this spectacular wonder, I would have had no trouble visualising the scene of the crime.
In normal Christie style, all of the evidence is laid out before us and I still was none the wiser as to the murderer until dutifully informed by Monsieur Poirot along with the rest of the dumb struck and gapping cast. I need to read more of these and maybe I will get a little wiser.
