While driving to their friend Bill Wong's long-awaited wedding, Agatha and her assistant, Toni, are thinking of what the beautiful bride will be wearing, when a terrified young man comes running down the country lane towards them wearing nothing at all. The encounter leads them to a naturist group, a disappearing corpse, an ice cream empire, and murder. But in this 33rd outing (following Down the Hatch), when Agatha begins to close in on a murderer, the sinister nature of the ice cream business leads her to a chilling conclusion.
