What could be more fun than a destination wedding, especially on scenic Cape Cod? Three-Zee Zook and her best friend, Bambi Bamberger, along with other friends and relatives visit the cape for the wedding of Three-Zee's aunt, looking forward to a week in the sun and surf, and wind up trying to solve the murder of an elderly couple after their ghosts show up near an iconic lighthouse. Complicating the issue even more is the mysterious appearance of the ghosts of passengers from a shipwreck, especially because the shipwreck occurred in November of 1898.
