Red sails to Capri

the long version

"The minute he saw the boat with the red sails moving into the harbor of Capri, Michele knew that something exciting was going to happen. But how could anyone know that three strangers - one searching for beauty, one for adventure, and one for "something difficult to explain" - would find the secret of the mysterious cove (the Blue Grotto) and so change the whole life of the island? A crisply told, exciting story, sparkling with good talk and the sunshine and color of its romantic setting." -- Jacket flap.
