Mistakes Mean Murder

Three women, all named Gloria Hebblethwaite, are pronounced dead on the same day and it looks a lot like murder.
Alice Valentine and Marmaduke Featherstone investigate only to find themselves involved in a family feud that has been decades in the making.
Meanwhile, when members of the local WI receive poison pen letters regarding an unsolved murder from thirty years ago, Marmaduke is asked to find out the sender. However, the case hits close to home since it is connected to the disappearance of his niece.
As rivalries are exposed, the residents of Partridge Mews are about to find out that secrets cannot be kept forever, and sometimes the dead don't stay buried.
