Paddington Bold  Suggested by SpideRaY 
Agenda Bold  Suggested by twinriver 
Museo Sans 700  Suggested by Fontbo 

I believe this font is Agenda Bold.

Maybe but the S and C are very different !!! , I have found a very similar font this is called Paddington Bold is a lot closer but still the kerning is not correct and S is totally wrong on the lead angle

I believe is more Agenda despite C character as SpideRaY says

I'd go with Museo Sans 700 for the SHERLO, the C appears to be a badly chopped O and the K has the cross stem removed. This will probably remain another unsolved mystery for Sherlock fans.
