Sherlock season 3 episode 3 is upcoming. Users who are living in UK can watch it on Sunday at 8:30pm. Because BBC takes internet censorship for copyright and doesn’t allow other countries IP to access that users have to get UK VPN and watch Sherlock season 3 episode 3. If you have’t found the link, please visit http://www.bbc.co.uk/iplayer/episode/b03ny7ng/Sherlock_Series_3_The_Sign_of_Three/. I think you can find many ways to watch Sherlock from some unfamiliar websites. Maybe those websites will ask you to install some plugins or software. I do not recommend people to watch videos from websites which require install something. It is possible that those websites will steal info in your computer.
If you haven’t found best way to watch Sherlock online for free, you can watch Sherlock full episode on Youku. But you have to prepare a VPN services including China VPN server. Because the video is only available in mainland China. Connect to China VPN and bypass the restriction.
