The Violins of Saint-Jacques

From amazon dot com: "This slim book starts with the meeting of an English traveler and an enigmatic elderly Frenchwoman on an Aegean island. He is captivated by her painting of a busy Caribbean port in the shadow of a volcano, which leads her to tell him the story of her childhood in that town back at the beginning of the twentieth century. The tale she unfolds, set in the tropical luxury of the island of Saint-Jacques, is one of romantic intrigue and decadence involving the descendants of slaves and a fading French aristocracy. Then, on the night of the annual Mardi Gras ball, a whole world comes to a catastrophic and haunting end." From Google Books: "Originally published in 1953, this novel was immediately hailed as a rare sweep of color across the drab post-war years. Fermor's writing about this tropical island is as beautiful and haunting as the sound of the violins rising from the water, which is all that remains of the island and its inhabitants."
