Sudden deaths and strange accidents have been occurring at the Mountain View Residential Manor in Kinross, a small town in Northern Tasmania. Sergeant Plate believes that because of the residents' advanced years and dependence on medication these are not unusual occurrences.
However, Dimpy Gruar, a sprightly but clumsy seventy-plus lady, and her friends, Judith Milner and Ronni Goodman, are convinced there is a murderer living in the Manor. Although she is trying to get her novella written, Dimpy is determined to reveal the identity of the killer and sets out to investigate ... before she, too, becomes a victim.
