On their arrival at the castle they learned that Buckingham and the king were hawking in the marshes two or three leagues away. In twenty minutes they were on the spot named.

On arriva au château ; là on se renseigna : le roi et Buckingham chassaient à l’oiseau dans des marais situés à deux ou trois lieues de là. En vingt minutes on fut au lieu indiqué.
