Killing Mr. Griffin. Killing Mr. Griffin is a 1978 suspense novel by Lois Duncan about a group of teenage students at a New Mexico high school who plan to kidnap their strict English teacher, Mr. Griffin. Duncan developed the story from the character of Mark, who is involved in the kidnapping plan and is based on the first boyfriend of Duncan's oldest daughter.
The prose of this novel was perfect--tense and terse, descriptive and darkly beautiful. I fell in love with this author and I will be looking for more of his work as soon as possible. But where Griffin really shines is his characters. There's Matt, struck by love at the worst possible time, and driven by a protective instinct he doesn't quite understand. And then there's stoic, silent John, a stalwart, steadfast survivor willing to do almost anything to get out of this mess alive.
