Sympathy for the Devil by Jerrilyn Farmer

Madeline Bean, caterer to the stars, is in the middle of the biggest job of her career. She and her partner Wesley have pulled off Hollywood's most outrageous A-list Halloween party for notorious producer Bruno Huntley, complete with an eerie fortuneteller who is astonishingly accurate, and exotic food that's to die for. Before long, Bruno is thrashing and writhing out on the dance floor. Just one problem: he's not standing up, And soon, he's not even breathing.

The newly late Mr. Huntley was poisoned, that's certain. But the number of suspects with a yen to send Bruno to the devil could fill an audition for extras in the next Quentin Tarantino flick. When Wesley is arrested for the murder because of a long-standing dispute with the maniacal mogul, Madeline knows he couldn't be guilty. But to prove it, she has to wade through the muck of a mudslinging family, outrun a pair of crazed canines, dodge a pair of well-aimed bullets, and expose a slew of secrets that could put a soap opera to shame. Somebody's cooked up a murder, and it's up to Madeline to find out who--before she faces a fadeout of her own.
