The ghostie

The little ghost lives in Uilenstein Castle. Every night, when the clock strikes twelve, he wakes up and happily haunts the castle. He has a bunch of thirteen keys, with which he can open all doors and chests. He most enjoys visiting his best friend, the owl Oehoe Sjoehoe, to reminisce about cannons, soldiers, wars, and a bet with a Count. The little ghost is very happy. However, he always falls asleep again at one o'clock... and he would so love to see what life looks like during the day. Just once. Will the little ghost succeed in becoming a day ghost? And what will people outside do when they see a ghost?
