An image of a screen - stay with us here - showing what's reported to be Thief 4 has made its way onto the internet.
The image shows a hooded character, who we're going to assume is series protagonist Garrett using a bow and arrow.
In the background a large, building with plenty of protruding ledges can be seen (anyone for some Assassin's Creed style climbing?).
Series fans will also note that the game seems to have dropped the first-person perspective in favour of a the third-person view. A decision that former Thief designer and BioShock creator Ken Levine might argue with.
Eidos Montreal has admitted Thief 4 is one "worst kept secret in the industry" and originally confirmed the title in May 2009.
