April Fool Dead [EPUB ebook] 
A Death on Demand Mystery

Someone is playing a rather nasty April Fool’s prank on mystery bookstore owner Annie Darling. A felonious forger on the idyllic — if rarely tranquil — South Carolina island of Broward’s Rock has made it appear as if Annie is accusing some of her neighbors of murder. In the wink of a bloodshot eye, the Darling name is mud . . . and then the Broward’s Rock body count starts mysteriously increasing. And now it’s up to Annie to follow the well-hidden trail of the vicious trickster — or a secret slayer’s next lethal "joke" may very well be on her!
