In addition to his library duties and his role as doting grandad, Charlie has enrolled in an early medieval history course offered by young, charismatic professor Carey Warriner. Charlie feels a bit out of place—his fellow classmates are half his age—except for Dixie Bell Compton, another "mature" student. When Charlie hears an angry exchange between her and their professor, his interest in piqued. He's even more intrigued when she shows up at his office asking for a study partner. Charlie turns her down and is saddened to learn just a few days later that Dixie has been killed.



Charlie wonders if Professor Warriner had anything to do with Dixie's death. Warriner is married to a fellow professor who happens to be a successful author. There are rumors on campus that their marriage was on the rocks. Was Dixie's death the result of a lovers' triangle gone bad? Charlie soon discovers that the professor's wife may have some secrets of her own, and his suspect list is only getting longer.



As he and Diesel step further into the tangled web of relationships, someone else is viciously killed. Whose jealousy finally erupted into murderous rage? Was it a crime of passion, or is there another more sinister motive? Charlie races to unravel this mystery: and to draw out the culprit, he may just have to put his own life on the line . . .
