I picked up three of these Diane Mott Davidson culinary mysteries last summer at the THS band garage sale. I just read the last of my three: Fatally Flaky.
It was simple but fun, and I wasn't sure of the killer until the end.
The heroine is a caterer who finds herself in the center of death investigations. Her husband is a homicide detective, so they kinda team up to solve the mysteries. Cheesy, I know. But entertaining. It's perfect for reading while falling asleep each night because it doesn't take a lot of brain power.
