If you're in the mood for a little Sherlock Holmes (or alternatively, feeling a little serial killing bloodlust, but let's go with the first one), you now have your choice of buying the full version of Sherlock Holmes vs. Jack the Ripper or try out the new playable demo.

Now shipping throughout North America and various parts of Europe, the fifth Holmes mystery from Frogwares pits the great detective against perhaps his most dangerous foe yet. As he did in real life, the ruthless killer known as Jack the Ripper is stalking the streets of Whitechapel in 1888, brutally killing prostitutes and confounding police. If there's one man who would be able to identify the mystery murderer, however, it's Sherlock, along with help from his trusty friend Watson and a little player guidance.

The demo takes place near the start of the game, allowing you to "witness Jack the Ripper's first murder as a spectator." The sampler also demonstrates the game's unique ability to switch at will from a third-person point-and-click control scheme to free-roaming, first-person 3D.

To download the rather sizable 872 MB demo, you can find it at standard download sites like GamersHell or WorthPlaying.
