midnight
There was but one thing to do ; the signal must be set this very night . The returning expedition from the south might even now be encamped at the High Bridge , and if Constans could help her at all it must be at once . Without waiting to parley further with herself , Esmay went to the door opening into the hall and looked out . The hour must be close upon midnight ; the house was quiet and dark . A piece of white cloth had been the signal agreed upon , and a fluttering handkerchief should answer the purpose well enough without being too conspicuous to alien eyes . Nanna still slept , and Esmay , slipping into the hallway , stood listening for a moment . Then she went on boldly ; the moon was still high , and she would not need a light .
