The Last Supper

Plot hole: The group poison a dozen or so people and dispose of their bodies by burying them in their own garden. Many of their victims are notable celebrities - television presenters, authors, leaders of large and vocal pressure groups. Not one of these people, not ONE, told their assistants or their secretaries where they were going and what they were doing on the night they were murdered? Not one single trace was left for the police to follow? Absolutely impossible.
