Murder Has Three R's

Twelve years after an attractive and well-off teenager is beaten and murdered by a group of female classmates, the instigators, now women in their late twenties, are dying. At first the fatalities appear to be unconnected and self-inflicted, including a drug and insulin overdose. But when a third ex-classmate, a woman managing an art gallery is strangled, newly promoted Inspector Tim Murphy suspects a cunning serial killer seeking revenge is responsible for all the casualties. Slowly, clues are uncovered that indicate the deaths must be linked.
