Holy Guacamole!

Description for HOLY GUACAMOLE! by Nancy Fairbanks:

Forty-something homemaker Carolyn Blue is through with cooking and cleaning. She's finally decided to throw in the dishtowel--and take on a dream job as food writer. Now her plate is filled with exotic locales, delectable foods, and even a dash of crime--to taste. She could very well get used to this...

Carolyn Blue spices things up at a post-production opera party in El Paso, Texas--where the company's notorious artistic director, Vladislav Gubenko eats some bad guacamole that disagrees with him right to the death. A scorned soprano admits to maliciously mixing the dish to get back at Vlad for passing her over for her dream role. But Carolyn learns that foul play, not foul foud was the real culprit--and uncovers some unsavory secrets about Gubenko that lead to a full menu of suspects. Now, the heat is on as Carolyn tries to drop the curtain on a fiend with a taste for murder...

This is #6 in A Carolyn Blue Culinary Mystery.
