Sister Frevisse mysteries
by Margaret Frazer

Sister Jean has enjoyed some of the books in the Sister Frevisse mystery series by Margaret Frazer. Sister Frevisse herself is a devout nun who wishes to spend her days in prayer. But, alas, she gets dragged into one damn murder investigation after another. While these are definitely light reads, you will learn lots about later medieval abbeys and medieval law. Point of interest: Fictional Sister Frevisse is a shirt-tail relation to real-life Chaucer.
