In 1307 the full weight of medieval justice descended on the sleepy town of Hereford.  But this court wasn’t summoned to prove innocence or guilt. The man on trial wasn’t a murderer, or a criminal. In fact he wasn’t even alive.

This was a holy inquiry, called by the Catholic Church to prove whether a dead English bishop was actually a miracle-worker – and whether he should be made into a saint.

His case comprised several alleged miracles, the most notorious being the spectacular resurrection of a hanged man. A Welsh terrorist executed by the state, hanged twice just to make sure, this wanted criminal somehow came back from the dead. And now a papal court would use all the instruments of legal process – witness statements, forensic evidence, cross examination - to prove whether it was truly a miracle.
