The Ghost in the Castle

In the castle of Whiterock one is often struggling with a spiteful phantom that runs through its rooms terrorizing the guests. Exasperated, the owner of the castle relies on a team of ghostbusters who use "aspirators" but have a limited range (the ghost is captured only if it is in the same room).

To track down the invisible ghost, the ghostbusters use the clues it leaves behind in passing from one room to another. The spiteful goblin has fun indeed in touching, moving, dropping objects that it finds inside the rooms it passes through. After a sequence of these clues the hunters are able to understand in which room the phantom is located and to reach it, possibly using the dense network of secret passages of which the castle has.
