For generations, privileged young men have attended St. Oswald"s Grammar School for Boys, groomed for success by the likes of Roy Straitley, the eccentric Classics teacher who has been a fixture there for more than thirty years. This year, however, the wind of unwelcome change is blowing, and Straitley is finally, reluctantly, contemplating retirement. As the new term gets under way, a number of incidents befall students and faculty alike, beginning as small annoyances but soon escalating in both number and consequence. St. Oswald"s is unraveling, and only Straitley stands in the way of its ruin. But he faces a formidable opponent with a bitter grudge and a master strategy that has been meticulously planned to the final, deadly move.
