------------------------------------

The winter of 1353 has been appallingly wet, there is a fever outbreak amongst the poorer townspeople and the country is not yet fully recovered from the aftermath of the plague. The increasing reputation and wealth of the Cambridge colleges are causing dangerous tensions between the town, Church and University.

Matthew Bartholomew is called to look into the deaths of three members of the University of who died from drinking poisoned wine, and soon he stumbles upon criminal activities that implicate his relatives, friends and colleagues - so he must solve the case before matters in the town get out of hand...

In medieval Cambridge, believers in the theory of nominalism have set some colleges at the throats of those who believe them to be heretics, and Brother Michael, the Senior Proctor, has his work cut out to keep the peace. When a nominalist is murdered during a riot Michael is certain he will easily find the killer amongst the Dominicans, but before he can get any sense out of them his junior proctor, Walcote, is found hanged.

Matthew Bartholomew starts to investigate, delving into a case involving nuns and rivalry with Oxford, and finds that the murders are less to do with high-minded principles than they are with baser instincts...
