The Case of the Wayward Professor // School's Out! — Gareth P. Jones

When Dirk Dilly gets a call from a distraught wife, he does not expect much in the way of exciting crimes to solve, but he sets off to follow the husband anyway. He couldn't be more wrong and soon he is up to his scaly neck in stolen government secrets, wicked and treacherous dragons, and a confused Prime Minister's son. Of course, nothing is too difficult when you can rely on a good friend like Holly to help you out.
