What’s better than a Brad and Karen thriller from Geoffrey Cooper? A Brad and Karen and Martin Dawson thriller! If you read earlier books in the series, you know him as the soldier-turned-medical-researcher who is a good friend of Brad, and who has helped the duo out in the past. I always enjoy his scenes, and so I was delighted when he teamed up with them again, assuming he would once again heroically help them all work as a team to catch the killer, as he’s done before.

Well, the way it all works out in this book is a little different. But I can’t say how. Sorry, you’ll just have to read it. What I can say is that the book is about a mysterious killer who keeps striking important medical researchers. Brad and Karen’s theories regarding her motives are forced to evolve with each crime, until eventually the pattern emerges in an unsettling way.

But what I think I liked best of all about this book is what the title refers to. The betrayal in question could be multiple things, including one possibility that isn’t even connected directly to the killer. I like ambiguity and mystery, leaving things up to interpretation. For one thing, it’s what helps keep critics like me in business. 🙂

Jokes aside, this is another good book from Geoffrey Cooper. I have only one slight, nit-picky complaint. As always in Brad and Karen books, part of the fun is the good food the protagonists enjoy as they try to crack the case. But I felt like in this one, it was always a lobster dinner.

Now, lobster is no doubt a northeast staple, so I can’t claim its not authentic. But I want variety! One lobster dinner is okay, but can’t we have some other delicacies, too?

I kid, I kid. This isn’t really a complaint, or if it is, it’s only the kind of complaint a long-time fan of a series can make. Like the Star Wars fans who wish there was a movie all about Porkins or somebody; it’s the kind of complaint that comes from a place of love, and I always love reading a Brad and Karen adventure.
