Allergic to Death — Peg Cochran

Preparing calorie-conscious meals for the dieters of Woodstone, Connecticut, Gigi Fitzgerald knows a cheater when she sees one. And when murder is on the menu, she's ready to get the skinny on whodunit...

Business is looking up for Gigi's Gourmet De-Lite, thanks to her newest client, restaurant reviewer Martha Bernhardt. Martha has the clout to put Gigi's personal meal plans on everyone's lips. But instead of dropping a few pounds, Martha drops dead from a severe peanut allergy...right after eating one of Gigi's signature dishes.

When the distractingly debonair Detective Mertz identifies traces of peanut oil in Martha's last meal, Gigi suddenly finds her diet catering business on the chopping block. Now she'll have to track down who tampered with her recipe before her own goose is cooked.
