five o'clock
She remembered vaguely one hundred twenty-one , and was sure that cousin Will Banning lived on East Seventy-second Street . But was his number one twenty-one , or was it three hundred forty-something , and Cousin Alice 's one twenty - one on One Hundred and Second Street ? Was that east or west , and was it Cousin Alice 's address before or after she moved last ? The more Betty thought , and the more certain it seemed that she could not reach Mr. Blake 's office by any route before five o'clock , the more confused she became . She had never been about in New York alone , and she had a horror of going in the rapidly falling dusk from one number to another in a strange city , and then perhaps not finding her cousins in the end . Then there was nothing to do but stay at a hotel . Luckily Betty did remember very distinctly the name of the one that Nan often stopped at alone .
