When Heather and Amy decide to take a yoga class at their neighbor's studio, they wind up investigating the disappearance of an instructor. When the man is found dead, their missing persons case turns into a murder investigation. They suspect it was one of his students, but which one? Who had the strength to kill? Armed with her Chocolate Peppermint Donuts, Heather is determined to figure it out. Join Heather as she exercises her brain and unravels the mystery! Praise for Susan Gillard:
