Twelve-year old Johnny Dixon and his friend Professor Childermass look for the hidden will left by an eccentric cereal tycoon who wished to make life difficult for his heirs after his own death by suicide.

John Bellairs is beloved as a master of Gothic young adult novels and fantasies. His series about the adventures of Lewis Barnavelt and his uncle Jonathan, which includes The House with a Clock in Its Walls, is a classic. He also wrote a series of novels featuring the character Johnny Dixon. Among the titles in that series are The Curse of the Blue Figurine; The Mummy, the Will, and the Crypt; and The Spell of the Sorcerer’s Skull. His stand-alone novel The Face in the Frost is also regarded as a fantasy classic, and among his earlier works are St. Fidgeta and Other Parodies and The Pedant and the Shuffly.

Bellairs was a prolific writer, publishing more than a dozen novels before his untimely death in 1991.
