 The unknown author of "L'Histoire de Guillaume le Maréchal" suggests that Marshal's disgrace was because he had indulged in a clandestine affair with Queen Margaret.David Crouch, one of the Marshal's principal modern biographers, argues that the charge against William was actually one of "lèse majesté", brought on by Marshal's own arrogance and greed.By this account, the charge of adultery was only introduced in the "Life of William Marshal" as a distraction from the real charges, of which he was most probably guilty.
