Ghost in the Attic

A young boy hears someone or something calling his name in a hushed tone. Is it a ghost in the attic of the old beach cottage he and his family live in? Legend has it there was a man who would swim naked in the Patuxent River and they say he could hold his breath so long he could sleep underwater overnight. Some local fisherman say they caught the River Man on their trotline many years ago when his mouth got stuck on one of the baited lines. One fisherman says the River Man died that day and to avoid trouble with the police, they hid the body in the attic of an old beach cottage along the river. Could this be the River Man's ghost come back to get revenge? Does he think Joey is kin to the fisherman who found him so many years ago?
