Alex Cassidy, a fifteen-year-old, must adjust to life at a Chicago boarding school (St. Andrew's School for Boys) while his parents fly around the world as travel-tour directors. To his horror Alex soon discovers that too many boys turn up dead or missing at the century old school--too often. With the aid of his roommate, Ziggy, they attempt to solve mysteries of the prestigious school. Do crypts under the Cathedral contain more than ancient bones? Will Alex survive his junior year?
