This delightful Catholic book features young Harry Dee, who arrives at St. Maure’s thin and pale from his painful experiences involving the murder of his rich uncle. In this last book of the trilogy, Tom and Percy help Harry recover from his early trauma—which involves solving “the mystery of Tower Hill Mansion.” After many wild experiences, the three boys graduate from St. Maure’s and head toward the life work to which God is calling each of them as young men.
