1579, St. Andrews. A thirteen-year old boy meets his death on the streets of the university city of St. Andrews and suspicion falls upon one of the regents at the university, Nicholas Colp. Hew Cullan, a young lawyer recently returned home from Paris, uncovers a complex tale of passion and duplicity, of sexual desire in tension with the repressive atmosphere of the Protestant Kirk and the austerity of the academic cloister.
