Seven o'clock
Jacob loitered about the town and docks when his master did not want him , and got exceedingly weary of his idleness . `` Eh , ma'am , '' he said one day to their landlady , `` my arms fair ache with hanging down and doing nothing . '' Thus things went on for about a fortnight , when one evening at tea-time Frank failed to make his appearance . Seven o'clock , then nine and ten , but no master came to remove poor Jacob 's misgivings . At last , about midnight , a stumbling against the door and a violent knock made his heart die within him . `` Who 's there ? '' he cried , before opening the door .
