Whole Enchilada
"Goldy Schulz knows her food is to die for, but she never expects one of her best friends to actually keel over when she's leaving a birthday party Goldy has catered. At first, everyone assumes that all the fun and excitement of the party, not to mention the rich fare, did her in. But what looks like a coronary turns out to be a generous serving of cold-blooded murder. And the clever culprit is just getting cooking. When a colleague-- a woman who resembles Goldy-- is stabbed, and Goldy is attacked outside her house, it becomes clear that the popular caterer is the main course on a killer menu. With time running out, Goldy must roll up her sleeves, sharpen her knives, and make a meal out of a devious murderer, before that killer can serve her up cold" -- from publisher's web page.
