Maltravers appears to have come back with Mortimer and
Isabella of France in October 1326, receiving restitution of his lands in 1327, with a grant out of the lands of Hugh Despenser. On 3 April he was appointed one of the keepers of the deposed king
Edward II, the other being his brother-in-law
Thomas de Berkeley, 3rd Baron Berkeley.
Adam Murimuth says that Edward was killed by order of Maltravers and Thomas Gourney, but later scholars doubt this. Maltravers and Berkeley remained in charge of the body until its burial at Gloucester on 21 October. During the next few years Maltravers was employed on commissions of
oyer and terminer. In that of February 1329, with
Oliver de Ingham and others, he was appointed to try those who had supported
Henry, Earl of Lancaster, in his intended rising at
Bedford. He was also on several occasions a
justice in eyre for the forests, and was in 1329 made keeper of the forests south of Trent. On 4 April 1329 the pardon granted to him two years earlier was confirmed, in consideration of his services to Isabella and the king at home and abroad. In May he accompanied the young king
Edward III to France; and the next year was steward of the royal household. ==Exile==
