technically this is not a whodunit. it's not something you figure out, in a real whodunit, like agatha christie, all the information is given to you so you can try to solve the puzzle, but these movies, are more like howdunits. you just enjoy the twists as they withhold information so you can enjoy the surprises. I do enjoy these, though these are kinda a new breed of mystery movies, mot like traditional whodunit, these are more akin to oceans eleven, where you just watch how it's all done and how cool and fun it all comes together.
