Murder At St. Mark's

Dr. Wignall, Headmaster of the venerable public school of St. Mark's, is fiercely proud of the institution. But this pride has been considerably shaken by the murder of a teacher's daughter in the nearby woods. As Mr. Prenderby, the charismatic master of North House, uncovers a sordid undercurrent of gambling, blackmail and immorality amongst the schoolboys, another murder is committed - this time, one of the pupils. When one of the teachers bolts, the police think they are trailing the killer - but are they?
