When Heather Shepherd picks up the newspaper, the last thing she expects to find is a report about the murder of a local businessman in his own home. She's shocked - why hasn't Ryan called her? That shock transforms into irritation when she realizes that her husband is trying to 'give her a break' from the one thing she enjoys - solving cases. Heather is determined to figure this one out and sets off on a Christmas sleuthin' adventure, armed with a box of her Christmas Donuts and a lot of help from her ever-sarcastic bestie. This one should be easy - all the suspects were in the house at the time of the victim's death. Except it never is: some suspicious internet activity has invoked the involvement of the FBI and they make it clear, Heather's special brand of investigation, isn't welcome. Heather's caught between her integrity and the desire to have a care-free Christmas. She's got to solve the case before the FBI and the local authorities botch another investigation.
