"Janet Markham Bennett is just starting to feel as if she’s getting used to her part-time job with her husband Edward’s top-secret government agency. Their next assignment is something a bit different, though. This time the agency is sending them to the Bahamas to spend a weekend on a private island. Instead of being given a specific job to do, they’re simply asked to keep their eyes open while they’re there.
In spite of the rather vague assignment, neither Janet nor Edward is expecting their host, Arthur Farnsley, to get murdered within hours of their arrival on the island. To Janet it seems as if there are far too many suspects but no clear motive."
