In June 1826 in a small settlement outside Sydney, Australia, a local farmer named Frederick Fisher suddenly disappeared.  Two months later a neighbor of the missing man was walking home late at night when he crossed a bridge near Fisher's farm.  Sitting on the railing of the bridge was the ghostly image of Frederick Fisher.  As the neighbor looked on in horror, the ghost raised his hand and pointed to a nearby creek before disappearing.   The next day, the police acting on the report of the spectral sighting went the bridge and searched the creek.  Along the bank the searchers discovered the body Frederick Fisher in a shallow makeshift grave.  Officials quickly arrested another local farmer who confessed to the murder and was tried, convicted and hanged.  It seemed that the ghost of the dead man had returned from the grave in order to solve his own murder.
