Diane Mott Davidson has written a culinary mystery series, and I have read quite a few of the books from this series. I find them highly entertaining and have enjoyed every one I've read up to the present time.
Goldy Schulz runs a catering business. In Killer Pancake, she is hired to concoct a low-fat menu for a cosmetics company. Not the easiest task for a caterer, but Goldy is up for the job. When a saleswoman for the cosmetics company winds up dead, Goldy's sleuthing skills are put to the test to see if she can come up with the killer.
Goldy is a fun character, and I really get a chuckle out of reading about her adventures catering different affairs. The author also includes recipes in her novels, which make the story even more interesting. I haven't actually tried any of them yet, but some of them do sound scrumptious.
If you are looking for a lighthearted murder mystery and like reading about food, Killer Pancake would most likely interest you, as would any of the books from Diane Mott Davidson's culinary mystery series.
