At least one of the early Plantagenets (maybe Edward II) was killed by his wife (he must have been really bad in bed) and her lover by having a red hot iron shoved up his ass. It was said you could hear his screams throughout the castle.
This was done so when the body was displayed it had no obvious signs of violence done to it.

And after Edward II's death, he was laid to rest in Gloucester Cathedral. The murderers wanted to make it look like he had just died, so they arranged for stately burial and proper Mass to be said for his soul, as befitted a deceased king. All part of the pageantry, what.
Isabelle of France, who deposed her former husband and ruled as regent along with her lover, Mortimer, was subsequently deposed by her son Edward III (she is suspected of having organized the murder of Edward II in order to put Edward III on the throne, but it doesn't seem to have worked out that well for her in the end).
Meanwhile, considering that kings were considered ordained by God (even the ones that abdicated and were murdered), dead kings were treated by the public as kinds of saints, and so pilgrimages were made to Gloucester Cathedral to petition the late Edward II to intercede with God for good fortune. The establishment of Gloucester as a pilgrimage point was very good for enriching the Cathedral (you'd almost think Wragg's relatives might have been Abbots there or something).
I had the pleasure of visiting Gloucester last year, and here Edward is:
Gloucester Abbey (as it was then) convinced Henry VIII to establish it as a Cathedral of the Church of England, and established a school (The King's School) in Henry's honour, which also continues to operate to this day. And so Gloucester escaped the destruction of the Abbeys (again, I suspect one of Wragg's ancestors of being part of the negotiations with Henry).
