I can't remember the name of the manga though. The original mangaka is listed as the 'original' on the front page but the actual mangaka is someone else. Not sure if they collaborated or something.

((And yes! It's Sherlock. I finally started watching the series tonight and laughed my ass off during the restaurant scene...and woke my dad up from my cackling. Oops. I watched the pilot version though, will begin watching the actual 90 minutes series tomorrow. The Sherlock in my sig is from the manga version of the series~))
