Great mystery. Surprise ending on who done it.
From Publishers Weekly
Fans of the late Virginia Rich's Eugenia Potter series (The Nantucket Diet Murders, etc.) will be pleased to learn that Genia is back, cooking and sleuthing up a storm in the coastal town of Devon, R.I., where she's come for the summer to help various needy family members, notably teenage great-nephew Jason, who may be violating his probation agreement after a marijuana conviction. Genia plans to host a special dinner party with an old friend and town leader, Stanley Parker, at her rented cottage, but when someone bashes in Stanley's head, Jason, alas, is way up on the suspect list. Investigating on her own, Genia learns that many Devon locals might be more comfortable with Stanley dead. A second murder thickens the broth. While the plot lacks suspense and the secondary characters tend to be caricatures (the flamboyant alcoholic, the devoted swain, etc.), Edgar Award-nominee Pickard, author of the Jenny Cain series, provides mouth-watering descriptions of such Rhode Island specialties as doughnuts and gingerbread, along with recipes for culinary delicacies like ginger carrot soup and lobster bisque.
An avid cook and recipe collector, Stanley Parker has roped Genia Potter into collaborating on The Secret Ingredient Cookbook, chock-full of Rhode Island culinary mysteries. Stanley invites six selected guests to test some recipes and solicit others. However, has one of the guests concocted a secret recipe for murder because Stanley is missing from the dinner.
