The Secret Ingredient Murders synopsis: Summoned from her Arizona ranch to take charge of her teenage great-nephew and his twin sister, Genia Potter takes a rental on the Rhode Island coast. Old acquaintance Stanley Parker is only too happy to welcome her. And soon Genia is busily preparing for the tasting party that she and Stanley are hosting that evening at her cottage.
An avid cook and recipe collector, Stanley has already roped Genia into collaborating on The Secret Ingredient Cookbook, chock-full of Rhode Island culinary mysteries. Now is their chance to test some recipes and solicit others from each of the invited. Stanley has carefully selected six guests. And each has been asked to contribute a recipe with one secret ingredient. Genia asks no questions–until the lobster bisque is cold and all but one are present. Where is Stanley? Dead. And unlamented. Has one of the guests concocted a secret recipe for murder? Everyone has a motive. And everyone has a secret–including Genia’s troubled great-nephew, the prime suspect. . .
