The Ghost Hunter

A ghost hunter is called to a house where two warring ghosts keep the occupants in terror each night. Objects fly around the rooms, pictures crash from the walls, and endless moaning and groaning is heard. The ghost hunter strolls around the place and makes a big deal of waving his arms about and shouting strange evocations.

Just as an afterthought, or so it seems, he gives the occupants - a mother and her teenage daughter - a bag of herbs so they may make a tea to calm their nerves.

They drink their tea, they go to bed, and both sleep soundly - the warring ghosts have disappeared.
