about ten o'clock
Nina complained of a headache when they reached home , and went early to bed . Harriet , when she had tubbed and changed to an evening gown , glanced in at Nina , and thought the girl asleep . There were men guests for dinner , and afterward there was bridge . Harriet sat with Madame Carter for awhile , for the old lady had also dined upstairs , went about the house upon her usual errands , and , going to her own room , found Nina reading , at about ten o'clock . Nina did not look up or speak as Harriet came in . The door that led to Richard 's room was not only unlocked , but actually ajar . Harriet gave it a surprised glance , and spoke to Nina , in the next room .
