Harry Thompson That's part of the experience of a thriller/suspense book or movie. If the author gives you a few subtle hints it let's you start weaving the ending. You know.... don't go into the shower the killers in there. If they had just followed the normal life of someone and then just had them killed off in the shower with no hint of a killer on the loose, we would be like wow, that was boring, sucked, and bam out of no where they were killed. But hey, I didn't see that coming!
