H. Bagwell Glomus built an empire out of cereal. In the 1920s, his Oaty Crisps were the most popular breakfast in the United States, and Mr. Glomus was the wealthiest man in the little town of Gildersleeve, Massachusetts. But he was not a happy man. In 1936, he took his own life and his will was never found. Legend has it that his last will and testament is hidden somewhere in his office, but so far, no one has been able to find it and claim the $10,000 reward. Yet, no one has looked as hard as Johnny Dixon.

A precocious young boy who's happier reading old books than playing outside, Johnny has a best friend in the eccentric old Professor Childermass, who knows every detail of Mr. Glomus's story--except the location of the will. Together, along with a new pal from Boy Scout camp named Fergie, they intend to crack the puzzle--but before they can claim their prize, they must defeat an ancient evil force: a living mummy intent on destroying them.

From the award-winning author of The House with a Clock in Its Walls, the Johnny Dixon stories are a refreshingly old-fashioned series of adventure and supernatural mystery. In the world of young adult suspense, few authors have the magic touch of John Bellairs.
