They met under very unusual, one might say detective, circumstances - a policeman and an artist, both of whom had recently experienced great grief. By chance, finding themselves at sea, on a yacht, cut off from the rest of the world for a long time, Susan and Frank soon realize that the passion that flared up between them almost in the first minute of their acquaintance has grown into a deep, tender feeling. In a tense situation, sometimes fraught with mortal danger , the heroes have to solve psychological puzzles, overcome the resentments and mistrust that separate them, and find a way to each other. For a wide range of readers.
