Wicked craving / G.A. McKevett.

Enhanced descriptions from Syndetics:

Dr. Robert Wellman claims his breakthrough hypnosis techniques can help anyone shed unwanted fat in record time. But while countless weight-challenged folks have flocked to his popular clinic, most have only lighter wallets to show for it. Still, Dr. Wellman seems to have it all, until his wife Maria is found dead at the bottom of a cliff outside the Wellmans' seaside estate-and it's clear she didn't go down without a fight. Savannah is more than happy to help her good friend, Detective Sergeant Dirk Coulter, investigate Maria's untimely death. The clues all seem to point to murder, from the broken statuary to the trampled flowerbeds surrounding the deadly precipice. And since Dr. Wellman appears to be the only viable suspect, Savannah is sure it's an open and shut case. But she's about to learn that appearances can be oh-so deceiving. Pound for pound, this is shaping up to be one of Savannah's toughest cases ever. But she'd better find the killer soon¿or else the bodies will just keep piling up¿
