Every summer for the past 10 years, six awe-struck bakers have descended on the grounds of Grafton, the Vermont estate that is not only the filming site for "Bake Week" but also the childhood home of the show's famous host, cele- brated baker Betsy Martin. The author of numerous best- selling cookbooks and hailed as "America's Grandmother," Betsy Martin isn't as warm off-screen as on, though no one needs to know that but her. She has always demand- ed perfection, and gotten it with a smile, but this year something is off. As the baking competition commences, things begin to go awry. At first, it's merely sabotage, but when a body is discovered, everyone is a suspect.
