THE best thing either Alice White or Malcolm MacGregor has ever done. While the A.E.F. tears up Paris, a disillusioned doughboy, seeking death in the trenches, finds love and laughter with a little Parisienne who makes "Mademoiselle from Armentierres" look for her chapeau. Director George Melford, in carefully blending drama, emotion,
and humor, has turned out a well-rounded production.
