midnight
He listened to the moving feet for a few moments . Then the noise ceased , but Harley knew that there was no further chance of sleep for him , with his nerves on edge , and likely to remain there . He lay back on the edge of the bed , trying to accustom his eyes to the darkness , and presently he heard a sound , the most chilling that a man can hear . It was the sound of a woman , alone and in the dark , between midnight and morning , crying gently , but crying deeply , uncontrollably , and from her chest . Harley 's resolve was taken at once . He slipped on his clothes and went to the door . His eyes were used now to the dark , and there was a window that shed a half-light .
