No virgin island : a Sabrina Salter mystery
(Book)

Sabrina Salter traded a high-pressure job as a Boston meteorologist for life as an innkeeper on St. John. But storm clouds roll in when Sabrina finds Carter Johnson, her most attractive guest, tucked up in a hammock way past check-out time and he's not just dead to the world, he's just plain dead, with a bullet hole in his chest.
