Ships sheeps passing in the night
(Book)

"It's springtime in Martha's Vineyard, and Priscilla attends the annual Lambapalooza festival going on at Derry Wilson's farm. When a cryptic message is sheared into Derry's prize sheep Sally, just as the animal is about to go into the auction, Priscilla -- aided by Gerald and her cousins -- sets out to find out who's behind the prank. Is it the animal activist who pickets the event each year, the rival farmers with a history of conflict with Derry, or someone else intent on mischief? Meanwhile, something is troubling Gerald, and Priscilla finds it almost as much of a mystery as the sabotaged sheep. Can she uncover the answers to both puzzling mysteries?" -- back cover.
