The killer may be a member of their tour group, a gypsy from a nearby camp, or any of four other people they've met since their arrival. There are motives galore. The murdered tourist has insulted practically everyone, her sisters have a monetary interest, and there may be a drug connection.
This story takes the group from Milan to Venice, Florence, and Capri. The action takes Dotsy and her friends on a gondola ride around Venice and through many of the sights of Florence: the Accademia, the Uffizi, the Arno river, the Piazzale Michelangelo, the ,a gypsy camp, and the caserma of the carabinieri.
