to Steventon, however, these details "turned out to be a pack of lies." MacDowell admitted their affair but has not spoken about the case since then except to deny any involvement. Investigation The revelation of MacRae's four-year affair with MacDowell led senior officers to admit that the case was "mired in a sea of deceit and untruthfulness from its start." Detective Sergeant John Cathcart coordinated the search and after eight months he had a breakthrough. While excavating Dalmagarry quarry he was hit by a stench after removing a layer of topsoil. Convinced it was a sign of corpses, Cathcart continued digging, but was told by a superior officer to stop as the bulldozer they were using had to go back to the contractors due to short funds.
