In 2002, the actor John Challis, the owner of the remaining buildings of Wigmore Abbey, invited the BBC programme "House Detectives at Large" to investigate his property. During the investigation, a document was discovered in which Mortimer's widow Joan petitioned Edward III for the return of her husband's body so she could bury it at Wigmore Abbey. Mortimer's lover Isabella had buried his body at Greyfriars in Coventry following his hanging. Edward III replied, "Let his body rest in peace." The king later relented, and Mortimer's body was transferred to Wigmore Abbey, where Joan was later buried beside him.
