Ballyfortnum Get Slim group—putting the die in diet.

In the close-knit Irish Village of Ballyfortnum, getting slim might just get you dead. Mystery-lover Jess O'Malley is distraught when her elderly friend dies, but that's not all—he's the third of the local slimming group to die this year and it's only February. Is something amiss in the Get Slim group?

Jess, aided by her sidekick Fletcher, her boisterous Labrador, must convince local policeman Marcus that there may be a murderer at large in the village. If she doesn't solve the mystery, will another of the dieters end up dead? Or worse—if she doesn't stop asking awkward questions, will Jess become the next victim?
