Presence of Mind — Fred W. Hunter

FINAL PERFORMANCE
Chicago police detective Jeremy Ransom knew his case was headed for the unsolved files: the victim had no enemies, there were no clues, nor motives. In a big city there was always another violent death, and though the murder rate was alarming, the crimes appeared unrelated.

At first, Emily Charters wondered if she was going dotty. But the septuagenarian with the razor-sharp mind had made the connection. She'd seen the victims she was reading about when she had attended a little theater production.

What had they all seen, other than a show? How did the killer know who they were? One thing was certain -- Emily Charters was about to turn Jeremy Ransom's luck around, providing a killer didn't come between them.
