On an antique hunt for a wealthy client, consignment shop owner Jennifer Shannon comes across a great buy for the medieval league fighter: a replica of a knight’s suit of armor. But they’re in for a surprise: it’s authentic, it’s worth a fortune, and encased within it is the corpse of a local Professor of Medieval Studies who’d coveted the treasure for himself—only to be bludgeoned to death with a spiked mace. The value of the combat armor is motive enough for Detective Lynwood to run with. Not for Jennifer—especially after she’s sent a varsity t-shirt splattered with the professor’s blood. Someone’s being schooled in crime, and Jennifer soon learns that the professor’s death is only the beginning of a lesson in murder.
