A young boy discovers a clue that points to an incredible treasure…

When Miss Eells gives young 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 then why do things suddenly start getting so strange? And terrifying?
