Inspector McClue: Death by Chocolate

From the back of the box:

Everyone's a suspect when murder is on the menu. And with a Classic Detective Murder Mystery you have everything you need to serve up the perfect murder dinner party. First the invites, you choose which of your friends play which devious suspect and invite them to come along as that character. Then the shopping list, menu suggestions and recipes. Plus of course...a really tasty murder to solve. It will be drop dead fun, and by the end of the evening, one (or more) of the suspects, your 'friends', will be caught out as the murderer!
