eleven o'clock
`` There is a train that leaves here at nine-thirty , a mad little ramshackle train that goes to The Ghost and back in an hour and a half . We 've all yearned to climb The Ghost , or as much of it as we dared . Now you two , with Mousey and a servant , are to go on the nine-thirty . I 'll finish my destruction of the social system and catch the eleven o'clock train . We 'll have picnic lunch . They say there 's a dreadful cavern at the base of The Ghost that is corking for picnics , and then we 'll explore until we have to return . Any objections ? ''
