When John retrieves the tire iron from his car before entering the smack-house, there is a billboard behind him. The middle portion of the billboard has been torn down, revealing the old advertisement underneath. The combination of the new and old signs now read, "Information is power." This is the main plot of this story, as one man uses information to maintain power over the world via blackmail. See more »

Better than previous episode
28 April 2014 | by monsieurnikhil123See all my reviews

Well after completing three series i can say that so far the journey was extraordinary . Series 3 may not be the best series probably because of the second episode the three signs but the first and particularly the last one,his last vow were awesome. I fervently wish that the entire team of sherlock comes with a bang this time . And i can say that i am deeply satisfied how the series is running. Talk about favorites,Than my personal favorites were three episodes the Reichenberg falls , a scandal in Bulgaria and his last vow and the best series was undoubtedly series 2.I just hope that they never change the cast especially martin freeman
