Focus Home Interactive has just produced a demo for its upcoming PC adventure, Sherlock Holmes: Nemesis.

The game pits the pipe-smoking detective against Arsene Lupin, a renowned French burglar who plans to steal five priceless objects in five days, from the likes of the Tower of London and the National Gallery. Obviously your job is to stop the sophisticated swag grabber, while playing the violin and generally acting a bit moody.

Sherlock Holmes: Nemesis will feature a detailed and atmospheric nineteenth century London landscape, and apparently a variety of historical landmarks have been faithfully recreated. There'll be in excess of forty characters to interact with and interview, and your puzzle solving and reasoning skills will be tested to their limits.

It's a sizeable 650MB demo which features several hours of gameplay, and you can grab it from the link below.
