Murder Scholastic — Janet Caird

Murder was not included in the curriculum of Findlater's Academy, but somewhere in the school's dim shadowed halls a vicious killer lurked...

When Christina Graham found the body of her colleague, Joseph Walsh, an antique compass buried in his back, the faculty privately agreed that a lot of people might want the meddling old math teacher dead -- and that included David Ronaldson, who appeared mysteriously out of the rain on the night of the murder. The school now needed a math teacher in a hurry, and luckily David was qualified. A fortuitous coincidence...or was it? Who was David? And where did he come from? Despite her doubts about the new man, Christina found herself attracted to him, flattered, yet frightened by his ever-present attention. And then, suddenly, the killer was stalking Christina, and the small seed of doubt about David began to grow into a monstrous, evil flower...until the murderer made one last, desperate move.
