This is a cozy featuring Fonnie Beachum, a retired nurse recovering from a stroke.
She's in a nursing home, not because she wants to be there but she needs to be there.
For the physical therapy and the necessary help with daily living. She's determined to get out of her wheelchair and back on her feet.
When her roommate dies unexpectedly and mysterious notes start showing up on the community bulletin board, Fonnie feels there is a malicious hand at work in her nursing home. The problem is getting anyone to believe her before the killer strikes again.
This one kept me guessing until the killer was revealed. That's unusual for me. I can usually pin down the "bad" guy with no problem. I've been reading mysteries a looong time.
