Groslow (Twenty Years After) is the one that hurt Parry's brother's head when they were helping the king get away from the Scottish. D'Artagnan becomes the man's friend and finds him to be dull witted and eogtistical. He plays cards with the musketters as a cover to free the King. Cromwell had hired him to navigate the ship where he though King Charles would be assasinated. Groslow dies when his boat blows up. All others escape.
