A boy detective is on the hunt for buried treasure in this young adult mystery from the beloved author of The House with a Clock in its Walls. Anthony Monday doesn't have many friends, and his home life is a wreck. But he does have Miss Eells, the librarian at the Hoosac Public Library, and he has an adventure waiting for him right around the corner. When Miss Eells gives Anthony a job at the library, he thinks he'll just be dusting shelves and filing books. Instead, he discovers a hidden clue leading to the treasure of eccentric millionaire Alpheus Winterborn. Miss Eells thinks the clues are a practical joke left by the odd, old Winterborn before he died. But if that's the case, then why do things start getting so scary so quickly? The closer they get to solving the mystery, the closer Winterborn's evil nephew Hugo Philpotts lurks in the shadows, waiting to snatch the treasure out of their hands. This first book in John Bellairs's Anthony Monday Mystery series will have young readers on the edge of their seats, desperate to race ahead to the story's final surprise.
