Cookie Dough Or Die by Virginia Lowell

Olivia Greyson is the proud owner of The Gingerbread House--a quaint shop that specializes in all things cookie--and her best friend, Maddie, is her sidekick, baking up scrumptious treats for their cookie-themed parties. But now they must take a break from baking and turn their attention to recreating a recipe for murder...

No one is more shocked than Olivia when prominent business owner Clarisse Chamberlain is found dead. It was Clarisse who encouraged Olivia to open The Gingerbread House--and she was one of her best customers. The sheriff is ready to call the case a suicide, but Olivia's convinced there's a murder to solve.

Then word spreads that Clarisse left Olivia a large sum of money, along with a collection of valuable, antique cookie cutters. Suddenly, Olivia is the prime suspect, with some fingers pointing to Maddie when the local postman falls ill after sampling one of their cookies. If the cookie-loving duo doesn't find the real killer, their reputation--and quite possibly their lives--will be battered for good...
