I used to enjoy reading forensic type mysteries, but lately they’ve all gotten too gorey and there’s always the protracted part of them where the doctor winds up being part of the killer’s nasty crime spree and I just dislike those parts. One of my librarians suggested that I might enjoy medical thrillers and gave me this book to read. It’s a story of a strange organism that is killing astronauts. There is a lot of techie space trivia, a lot of astronaut background, a lot of sleuthing, and no bad guy hiding in the closet of an abandoned house while the doctor walks around in the dead of night. Quite good. Medical mysteries mean you’re usuallly racing against an unknown bacteria or virus, not another person and this gives authors like Gerritsen a much wider range of potential “bad guys” that can have alll sorts of differing characteristics. This puts an end to trying to figure out what terrible, horrible thing could have happened to the bad guy to make him into this wretched killing machine. In short, I enjoyed this new genre of mystery/thriller.
