Unemployed depressive Peter Ferguson hangs himself after apparently killing his four children with drug over-doses,though one,Callum,survives. However pathologist Duncan believes that Ferguson died some while before the children. Lou,the widow,was once the baby-sitter for a child who died in her care,whose mother never forgave her. Furthermore Lou was having an affair with work colleague Greg and someone alerted Peter to the fact. And Peter was due to give evidence at a tribunal over his dismissal. The truth,when it comes,is ultimately both simple and shocking,touching even the hard-nosed Burke.
