The Duppy Ghost is West Indian and can be summoned by a secret ritual to do the callers bidding.
The caller needs to throw coines and a glass of rum on a grave.
This causes a ghost to come out in such a bad temper that he will do any evil the caller asks.
According to beliefs, the Duppy Ghost is the personifacation of the evil in man.
People are warned against calling up this Ghost.
