Six o'clock
`` I have lost so much by boarders going away owing me money that I am obliged to ask gentlemen to pay in advance till I am well acquainted with them . '' `` That is quite right , '' said Frank . `` What is your dinner hour ? '' `` Six o'clock . We have lunch at half-past twelve for the ladies , but if any gentleman happens to be at home at that time , he can go in . '' Frank looked at his watch . It was only eleven o'clock and as so much of the day remained , he decided , as soon as he had unpacked his valise , to go downtown and look for a place without delay .
