To our Graves by Paul Nicholas Mason

Located just outside the village of Bath, Ontario, St. Cuthbert's College prides itself on its beautiful lakeside campus, rich academic curriculum, diverse sports and cultural programs, and stable of distinguished graduates. But when a seventeen-year-old student is found stabbed to death in the chapel, the school's management is desperate to separate itself from the crime, even though Detective-Sergeant Diane Stewart comes to believe the murderer is a member of the school community. A fast-moving tale of deceit and intrigue, To Our Graves is a thrilling crime novel set in an exclusive Canadian private school.
