Who pays the ferryman?
Ancient Greeks placed a silver coin in the mouths of the dead as payment to the ferryman, Charon, for carrying their soul across the Styx to the underworld.
Today, in France, the deceased take their jewellery or wallets with them, presumably for the same reason. One enterprising thief has forgone the labour involved in grave-robbing, by simply relieving the bodies of their travel allowance before burial.
Mind you, the suspect is in her sixties. There comes a time in everyone's life when digging up bodies just becomes too much.
