A Hercule Poirot Amuse-Bouche: The Adventure of the Egyptian Tomb by Agatha Christie

Do you believe in spirits? Well then M. Poirot believes in YOU.
Especially if you happen to find yourself in the vicinity of a
murderer willing to kill FOUR people (so... a serial killer) for
the slim possibility of a hastily scribbled note passing muster in
a probate court as a legitimate will. Join us on one of Dame
Agatha's early, pre-Mallowan, archaeological digs.... Hope the sand
and heat don't bother you as much as they do Poirot!
