Keyla and Sherlock were walking by the Old Schoolhouse when they heard a crash. They stepped inside the front door to see what caused it. The school hasn't been used in years, and a few spiders have moved in. Suddenly a gust of wind closed the door behind them. When they turned back towards the door, they found it locked with a message carved in the wood. "The door is locked, until the end of the day. Inside the house, you will stay. There is another exit, but it is hidden well, If you pay attention, the house will tell." Keyla and Sherlock are good at paying attention, but they will need some help to unlock the mystery of the Old Schoolhouse and find the hidden exit.
