For my story I wanted to hide a twist so the reader will not see it coming. The way some thrillers do it, is by using a red herring character to make the reader think he is the villain when it is actually someone else. However, there is only so much I can do to misdirect the reader. A lot of people are going to think the villain is the prime suspect naturally, so there is only so much you can to do to hide that. I could bring in a red herring to make it easier, but I am not sure how to do it without it coming off as forced. The only reason such a character is there, is to be a red herring, so how do you structure it so that he is naturally part of the story, and people will think it's him who is likely the villain, even though there is no reason for anything to point towards him naturally?
