It's about a boy that gets in trouble at the first day by riding on a locolmotive and got dirty and started with five demerits. He wanted fun at the academy so he had a secret candy store but he tricked the superintendent to get sports into the academy and then it became fun and Tom did not get expelled and he did not get any demerits for the rest of the year.
This one took about two weeks -- what fun to read about Tom and all of his schemes!!
