(From the publisher):
Mandie had been glad when her grandmother bought the building that housed the Misses Heathwood's School for Girls, and now Mrs. Taft is behind all the modernization of the school. With the installing of electricity and a furnace, workers had made holes everywhere, running pipes and wires through the floors, the walls, and the ceilings.
Celia and Mandie find that their room has a big hole in the floor and another one in the wall. What were the scary noises in the night? Did Celia really see what she thought she saw? And when Snowball disappears, do they dare search where they think he's gone?
What secret is the schoolhouse hiding?
