Four bright, lively and stubborn septuagenarians are stirred into action by an unexpected death in their retirement community.

Angela Benbow and Caledonia Wingate and two reluctant pals in their retirement community shrug off their infirmities and take to the investigative trail when one of their own, a not-so-sweet busybody named “Sweetie”, is found murdered on the beach.

The four not-so-gentle ladies realise what the young investigating officer has trouble accepting – that even the most seemingly docile among them may be provoked into taking a life, even a series of lives, if the pleasure of the time they have left is threatened.
