An Unwanted Guest

I finished this in one day, so it would seem that it should have 5 stars. But the characters are really just stock characters for the “group locked away” murder mystery. I wasn't expecting that. I think if I had expected that going into it, I would have liked it better.
Outside of the stock characters, I loved the setting and plot. I hadn't figured the answer out until late in the book. And the why was a mystery until I was told. There were hints, but I missed the early hints.
Good murder mystery in the vein of And Then There Were None or Murder on the Orient Express. But be prepared for stock characters.
