Before Lobelia Falls can have a museum, the curator's killer must be caught.
The Grub-and-Stakers gardening club has traditionally limited its activities to serving tea and gossiping about wildflowers, but when water department supervisor John Architrave is found murdered in the woods, club member Dittany Henbit turns to solving mysteries. After Architrave's will reveals that he bequeathed his ramshackle old house to the Grub-and-Stakers, with instructions for it to be turned into a museum, Dittany resigns herself to weeks of cleaning out the mansion and sorting through donated town 'artifacts.' The task turns interesting, however, the minute bodies start falling from the sky. The new curator is airing out the house's attic when he takes his tumble off the roof. So unlikely is it that he would fall out the tiny attic window, that Dittany has no choice but to attempt to add one captured killer to the young museum's permanent collection.
