six o'clock
So Prudence delightedly tripped up the parsonage board walk , wheeling the bicycle by her side . She hid it carefully in the woodshed , for the twins were rash and venturesome . But after she had gone to bed , she confided her plan to Fairy . `` I 'm going at six o'clock , and I 'll be back in time to get breakfast . But as you know , Fairy , my plans do not always work out as I intend , so if I am a little late , you 'll get breakfast for papa and the girls , like a dear , wo n't you ? '' Fairy promised . And early the next morning , Prudence , in a plain gingham house dress , with the addition of a red sweater jacket and cap for warmth , set out upon her secret ride .
