A series of books written by Susanna Gregory[[note]]Pseudonym of Elizabeth Cruwys[[/note]] that are set in the mid-1300s in and around Cambridge, England.

Matthew Bartholomew is a physician and a teaching fellow at Michaelhouse at the University of Cambridge. Unusual for his time and place, he believes that washing your hands does a lot more for your health than consulting horoscopes, which doesn't sit well with many of his contemporaries. He's also the somewhat reluctant crime-solving partner of another fellow at Michaelhouse, Brother Michael, a Benedictine monk with a love of politics, intrigue, and good food. Together, they fight crime as they solve the murders that plague their university town and elsewhere.

!! This series provides examples of:
* ActualPacifist: Master Kenyngham, who deplores any kind of violence and will always try to find a peaceful solution.
* BackAlleyDoctor: Though it doesn't quite fit, in today's society Robin of Grantchester would count. Surgery then was the work of barbers, not physicians, and thus they often didn't have much training. Robin is notorious in the series for losing (much) more patients than he saves.
* BadassBookworm: Many of the fellows and the students, including Matthew and Michael.
* BashBrothers: Matthew and Michael are a mild form of this, as this is how the town, university, and church view them with crime-solving abilities.
* TheBigGuy: Brother Michael, possibly to the extent of a GeniusBruiser.
** Also Langlee.
* BunnyEarsLawyer: Matthew is viewed by many as this due to his uncommon (but [[ScienceMarchesOn correct]]) medical theories, such as washing one's hands frequently and not drinking dirty water.
** Clippesby as well, who holds conversations with animals, but is a good music teacher, if not astronomy teacher.
* CannotSpitItOut: Matthew [[spoiler:towards Matilde, whom he loves. The day he finally decides to propose, she's already left town and disappears.]]
* ChristianityIsCatholic: This is over a century before Henry VII splits with Rome, so this was pretty much TruthInTelevision.
* CloudCuckooLander: Clippesby, overlapping with BunnyEarsLawyer.
** Matthew's student Richard Deynman shows signs of this.
* TheDungAges: In use, although with much more historical accuracy, as the author is a Cambridge scholar [[ShownTheirWork who has done her research]].
* FriendToAllLivingThings: Clippesby is a male example.
* TheFundamentalist: Father William is one. He's not a bad guy, just sees heresy everywhere, especially in the Dominicans.
* GoodShepherd: Master Kenyngham.
* HighClassCallGirl: Matilde, [[spoiler: although she's retired.]]
* HookerWithAHeartOfGold: Yvonne de Blaston, along with others in the Guild of the Frail Sisters.
* KilledOffForReal: Being a murder mystery series, you can expect a good many, even among regular characters.
* TheMcCoy: Matthew, definitely. Michael to a lesser extent.
* TheMiddleAges: Set in the 1350s in Cambridge, England.
* NoIndoorVoice: Father William
** The Michaelhouse Choir could count as well. What they lack in talent (which is a lot) they make up in sheer volume.
* PlagueDoctor: Matthew was one. [[spoiler:It nearly kills him in the first book.]]
* PoisonIsEvil: Used in several books to dispatch the victims.
* PutOnABus: InUniverse. [[spoiler:Father William gets sent away for about a year for causing problems and helping to incite riots over perceived heresy.]]
** TheBusCameBack
* ScrewTheMoneyIHaveRules: Matthew could become rich drawing up horoscopes for rich patients, but he'd much rather serve the town's poor and be paid nothing in return.
* ShownTheirWork: The author has done her research, and thus the time period is show with accuracy. The novels often come with their own historical notes to explain some of the things.
* TheSneakyGuy: Cynric, due to being a former soldier.
* SpeaksFluentAnimal: Clippesby, or so he thinks. The other fellows think he's insane.
* TechnicalPacifist: Brother Michael. Just because he doesn't like to carry arms doesn't mean he can't fight back. He is the son of a knight after all.
** Can apply to Matthew and the other fellows who are in religious orders.
* TookALevelInBadass: Matthew in the eleventh book, [[spoiler: after spending over a year abroad searching for Matilde, including France at the Battle of Poitiers, and has grown capable with a sword as a result.]]
** Michael as well [[spoiler: when he becomes the Senior Proctor of the University and begins gathering a power base.]]
* TruthInTelevision: There really was great conflict between the university and the town during the time period and later. Murders between the town and gown were common enough, and riots did take place.
* WellIntentionedExtremist: A few are met throughout the course of the series.
* UnresolvedSexualTension: Matthew and Matilde.
