Killing Mr. Griffin by Lois Duncan

Four students annoyed by Mr. Griffin, their English teacher, decide they want to kill him. Susan McConnell is one of Mr. Griffin's best students. So when her crush, Dave Ruggles, asks her to partake in the murder she hesitates before acceding. They plan for Susan to say she would like a conference and when Mr. Griffin walks out into the parking lot, the plan is to attack him there. So, after her meeting Susan tries to play it cool and hide her knowledge about Dave being in the backseat of his car. When Mr. Griffin attempts to get in his car, David jumps him throwing a bag over his head. They put Mr. Griffin in Jeff's car and start to drive away, only slightly covering the topic that Mr. Griffin may not be able to breath with the bag over his head. The beginning of the plan whizzes by flawlessly and Mark, Jeff, and Dave drove away with Mr. Griffin, taking him to an abandoned house and leaving him there. Unbeknown to them, Mr. Griffin passes away and when they do return, they must figure out what to do with their dead English teacher.
I think this book is very well written and has great details on the events of the matter such as kidnapping Mr. Griffin and the fight he put up, how mean he is to his students, the abandoned house and how they dealt with a deceased English literature teacher.
