The latter was sometimes disquieted thereby.

"Fear nought from my son of Navarre," said John; "he durst not vex you, for, if he did, he would have no greater enemy than myself." John did not yet know his son-in-law.

The King of Navarre, having notice thereof, instructed one of his agents, the Bastard de Mareuil, to go with a troop of men-at-arms and surprise him in that town; and he himself remained outside the walls, awaiting the result of his design.
