The Queen’s Man: A Medieval Mystery by Sharon Kay Penman (1996)
I will always have a soft spot in my heart for stories involving Eleanor of Aquitaine. Her biography has intrigued me since middle school, where I dressed up as her for a history project and made a pretty cool poster board. Eleanor was one of the most powerful women of the middle ages: she participated in the machinations behind two crusades, patronized the arts, supported a revolt against her second husband, and acted as regent when her son when off to fight in the Third Crusade. She married the king of France at 15, obtained an annulment 15 years later, and then married the much younger king of England with whom she had Richard the Lionheart and the infamous Prince John. Strong and intelligent, Eleanor was more than a match for the powerful men surrounding her, standing her ground against conspirators, war, and imprisonment. She captured the heart of my feminist 12-year-old self, which is why I still love reading about her, fiction or non.
The Eleanor in The Queen’s Man is nicely characterized, as is the young hero of the story, the illegitimate Justin de Quincy. De Quincy witnesses the murder of a messenger, and attempts to sleuth out the killer at the Queen’s request. The precarious political situation of the time (Richard has been captured; John is making nefarious plans) makes an excellent setting, and Penman’s deft writing and clear knowledge of the era makes this mystery well thought out to the end.
