ten o'clock
`` Go on . Say , this is great ! '' `` I want , '' Hunterleys explained , `` your yacht to take the place of the other . I want it to be off the Villa Mimosa at ten o'clock to-night , your pinnace to be at the landing-stage of the villa to bring Mr. Grex and his friends on board . I want you to haul down your American flag , keep your American sailors out of sight , cover up the Stars and Stripes in your cabin , have only your foreign stewards on show . Schwann 's yacht is a costly one . No one will know the difference .
