It seemed possible to me that Whitson was the fulcrum, the man who could connect everything. The strange omissions at the trial and in Helter Skelter; the blatant failures of LASO to follow up on good leads; the suspicion that Manson could be an informant; the murmurs about a narcotics deal gone south: if I wanted to construct a unified field theory, Whitson, linked to intelligence work by no fewer than a dozen sources, would have to be at the center.
