Two books and two frowns

I read a couple of crime books this week and for the most part both of the books progressed with intricate little plots and I wondered just what the answers would be. One book dismissed a subplot with an Oh, well, that was weird but it happened. The other pulled the two perpetrators out of the air in the last few pages, leaving all other suspects in the dust.

And you know what I am going to do? I am actually going to investigate questions on the Internet referring to any following books that might reveal what the unexplained weird phenomenon was. Because I am that crazy.
