Sherlock "His Last Vow"

Yup...borrowed the DVD for season 3 from a friend...finished watching it Friday night...and rarely have I seen a television episode with more twists and turns! I am pretty sure there are still parts of my mind strewn about my apartment, after my head exploded at the end of the episode! No spoilers...but will tell you to GO WATCH IT!!!!!!!!!!!!!!!!!!!!!!!!
