Walker's talked about the fact Frogware are "do"ing an improved version of their Sherlock Holmes: The Awakened previously, but there's now a just-over 500Mb demo of the game available. Also, in French. You can download it and play it and similar. This is becoming something of a trend, what with the Witcher's Enhanced edition and all that. And to that, we can say: Splendid.
If you need a reminder of the improvements, below the cut's the video Walker previously linked to.
And Good morning, everyone. I trust your day is splendid.
