Helen had just turned twelve. That evening on Tuesday October 19th, she had laid down early when her mother's voice awakened her. The voice came from the lower floor. "Helen, come down quickly to the kitchen. I want to speak to you" Helen, clearly annoyed and sleepy, came out barefoot and before her bare foot touched the first step, a hand pulled her violently back. It belonged to her mother, who was scared to whisper "I heard it too".
