The master of the house couldn't keep up with the digging of the holes by himself. The director ordered that the students of the Winterstein school should help to fill up the holes again. Everyone was wondering who could be behind this. Hey, maybe it's aliens who are looking for a crumpled space capsule. Yes, of course. And they put the master of the house to sleep with sleep lasers while he was watching. Nonsense. I'm sure there are archaeologists working here. I was at the excavations back then, in Egypt. We were amazed. Jewels, arm-tires, golden masks. Not bad, not bad at all, I tell you. A few meters away from them, director Siegmann was walking through the brown hill landscape with a sad face. Next to him, a strange man walked in and talked to him. He was an architect. Benny, Schoki and Henrietta could hear their conversation. They have to put an end to the spook, otherwise their school will collapse. This is a case for a special company. I know a construction company that is dealing with something like this. I believe, however, that nothing will happen this month. The company is completely booked out. The Moist Wall doesn't look good. If we don't get a construction team, what do we do? Find the perpetrator. No more holes are allowed. This is no longer a child's play.
