Záhada školní půdy - První čtení, to nic není – Pospíšilová Zuzana (2015)

Alenka is in the first grade and longs to experience an adventure. She confides in her classmates, and eventually, a search party is formed. But where can they find an adventure? They didn't come across anything during the day, so they decided on a night observation. During this, Alenka, who lives across from the school, sees a lit window in the school building. It's not a window in any classroom, but in the attic. The children decide to investigate it and secretly head to the attic after school. In the dusty room where the light was on at night, they don't notice anything unusual at first glance. There are only stuffed animals. But how is it that there's no dust on the table? This definitely needs to be thoroughly examined. Alenka, Jana, Adam, and Lukáš think about how to get into the school at night. Chance helps them. The teacher prepares a sleepover at school with lots of games and interesting competitions instead of the canceled school trip. On this occasion, the children manage to visit the attic at night as well. What they see definitely surprises them.
