Medieval murder maps of three English cities offer window into past

Online project draws on 700-year-old records of coroners' inquests in London, Oxford and York

Early on a Sunday evening in April 1299, a young scholar led Margery de Hereford inside a house in Oxford. What began with lust ended in murder: when Margery, a sex worker, demanded to be paid, the unnamed man drew a knife, struck her near the left breast and fled.

Margery may have never received justice but her story is to feature in a collection of interactive maps that use 700-year-old records of coroners' inquests to locate and detail homicides across three UK cities.
