Everyone had assumed that Mrs Humphrey had met an unfortunate and perhaps untimely end by the third day that she failed to show up for work. On the second day, a coworker went round her house to see if anything had happened to the elderly librarian. But she was not home, nor was there any sign as to her whereabouts, other than a hungry cat. Her son hadn’t heard from her, the women’s knitting group at church didn’t know she was even missing. But everyone was startled on day five, to find her upright, and dead in the 700 stacks.
