Brilliant writing, excellent acting and great suspense, as always. Nevertheless, I found very difficult to explain why the f*** sake did Walter, so careful and thorough, forgot that important object on the toilet! The guy, at this point, thinks of everything, every little detail, but he forgot that he owns a book given to him by Gale with a written dedication so explicit that could frame his ass so hard if found by his brother-in-law, whom weekly takes a dump at his house. I'm not hunting witches here guys, I'm not looking for flaws. I love this show so much that it kind of let me down on this one. Still, I forgive you.
