Every morning, without fail, Sue Marcum called her best friend, Larry March.
It was their routine — reliable as clockwork.
But one Monday morning, his phone never rang.
Unable to shake the feeling that something was wrong, Larry left work early and drove straight to Sue’s home in Bethesda, Maryland. She didn’t answer the door. He had a key, so he let himself in. What he found stopped him cold. Sue’s normally tidy home was in chaos.
Larry thought she had been robbed. But there was no sign of Sue.
