I read this book when it came out in 1990 and always remembered it fondly. Unfortunately, when I reread it recently I learned it wasn't as good as I believed. Laura Penn is dragged into a murder investigation when the prime suspect, her ex-husband, names her as his alibi, then asks her to play along. Laura is horrified, but doesn't believe him guilty so agrees. But when more murders occur, with her ex looking more and more suspicious, Laura begins to fear she made a mistake. Then there are the strange items that begin appearing in her locked home, items linked to each of the murder scenes. Detective Max Elliott knows Laura is lying about something. Can he get her to confide in him before she becomes the next victim?
