OK, finally got to see it. YAY! I loved all the classic JC elements, especially when he pulled the coat out of the closet. Yes, the MI5 bit at the end was a bit much but I really liked the locked room mystery. This time, I was totally off base. I knew the things in the closet were important but I couldn't figure out how. I was thinking he faked his death or something.
I really loved the humor in this episode; they got the tone just right. And Rik Mayall was AWESOME, rolling in and out of the scenes with such aplomb.
It makes me long for the old Jonathan Creek even more.
