Cait Morgan and Bud Anderson are finally on their long-awaited honeymoon, a cruise of the Hawaiian Islands. They have been enjoying the sites, the luxury of the cruise ship and each other. But as readers know, this crime-sleuthing couple are soon facing a death, getting themselves involved in the investigation while the ship sails to its final destination.
The Corpse With the Diamond Hand is the sixth in this series featuring Morgan, professor of criminal psychology at the University of Vancouver, and Anderson, a retired law enforcement officer. They seem a nice couple but I'm surprised that Bud feels so laid back while Cait is a bit of a rabid dog. Throughout this book we learn that Cait doesn't like to play with others, doesn't like to follow rules (such as those set by the ship's top investigator) and just plows her way through an investigation. She feels very much like an amateur sleuth, yet she should have enough experience to not do some things. Bud, who has much more experience, seems to be happy to take a back seat to Cait, which is strange.
The duo face an extensive group of suspects most with odd quirks (a woman who only wears beige and talks with her eyes closed, a husband who dresses as if he has never been around others, a rich couple who drink all the time), every one of course having a secret and a motive for killing the murder victim. There's also the limitations of an investigation on a ship set up to take care of minor illnesses and injuries. Despite that, somehow Cait comes up with everyone's secret and whether they are the guilty party.
And I didn't believe it. I didn't like Cait and didn't believe her so-called eidetic or photographic memory. She frankly is a know-it-all and I've usually found that such people make big assumptions, many of which are wrong. Cait and Bud have potential but right now they feel mismatched and awkward to me.
So the story is cute (definitely a cozy) and its fun to read but these characters just didn't hold enough of my interest to want to follow Cait and Bud into more cases.
