*See Also Murder*
Larry D. Sweazy
The story takes place in an isolated rural setting. Before the time of computers and word processors, people like Marjorie were needed to index books manually. They methodically put information into order, cross-referencing terms and finding relationships. I never knew how that was done.
Her neighbors are the first of several people murdered and because an unusual amulet is found, Marjorie is asked to assist with some research as her work as an indexer makes her good at that.
I enjoyed the mystery but was really captured by Marjorie's character and the description of the small town on the plains.
