Pyramids (Discworld)

"Look after the dead," said the priests, "and the dead will look after you." Wise words in all probability, but a tall order when you have just become the pharaoh of a small and penniless country whose largesse--and indeed treasury--is unlikely to pay for the construction of a monumental pyramid to honor your dead father. And particularly when your only visible means of support is a recently acquired qualification from the Guild of Assassins, an association wherein running a kingdom and basic financial acumen were not prerequisites for course entry.
