Bestselling mystery writer and amateur sleuth Jessica Fletcher is invited to travel to London on the grand dame of ocean liners, the Queen Elizabeth II, as one of seven guest lecturers. The night they set sail, a fellow speaker is found brutally murdered. Now Jessica has just four days at sea to find the killer...before she finds more of her colleagues, or even herself, dead in the water!
Agent Pendergast and Vincent D'Agosta team up once more to investigate brutal murders of a seemingly supernatural origin. Their investigation takes them from high society New York to old world Italy and into the dark heart of an age-old conspiracy. Vincent D'Agosta, Laura Hayward and Bill Smithback's nemesis, reporter Bryce Harriman (mentioned often in the previous books) make a reappearance. In this book the reader is introduced to Pendergast's brother Diogenes and D'Agosta catches his first glimpse of Diogenes.
