Banksiadale was an idyllic timber mill town, near Dwellingup and Pinjarra, in the south-west of Western Australia. In its heyday and climaxing in the early 1960s, it was the gem of all mill towns with its own electricity supply, piped fresh water to all houses and a peaceful, well-behaved community, not even needing a resident policeman. Today, it does not exist.
Everything changed in 1963 when the mill mysteriously burnt down, all workers had to leave, and the mill houses were swallowed up and covered by the waters of a new dam, the South Dandalup dam. Other problems emerged when it was discovered some 40 years later that two local residents had been murdered and disposed of in a mill house which was submerged along with other buildings when the dam was flooded. Three detectives have to work painstakingly on various clues to try to track down the killers in this cold case.
