Many medieval scholars discontinued their university studies before completing their degree. Some lacked funds; others became bored with a scholar's life. Occasionally these young men formed lawless bands, robbing and raping and creating chaos. They were called goliards.

In Deeds of Darkness Master Hugh learns that the Bampton coroner, an old friend, has been slain while traveling to Oxford. As he seeks the killer (or killers) he discovers a band of goliards in the area between Oxford and Bampton. But how to apprehend these youths? They have protectors far above Hugh's station. He must deal with the claims of justice on the one hand and the power of great men to protect their henchmen on the other.
