At some point during the long, long afternoon, Joyce Haney, wife, mother, vanishes from her home, leaving behind two terrified children and a bloodstain on the kitchen floor. While the Haney's neighbours get busy organising search parties, it is Ruby Wright, the family's 'help', who may hold the key to this unsettling mystery.
