The demo is afoot for Sherlock Holmes: Nemesis

For fans of Sherlock Holmes, it's time to put on your thinking deerstalker and dive into the newly-released demo of the great detective's latest case, Nemesis.

The fourth Sherlock Holmes adventure from Frogwares is a battle of the wits between Holmes and the renowned French burglar, Arsène Lupin. The demo takes place at the beginning of the story, as a quiet morning at 221b Baker Street is interrupted by a letter from Lupin, announcing his intention to steal five priceless artifacts from London in the coming week, and daring Holmes to stop him.

Nemesis, like its predecessor The Awakened, is a full-3D adventure that provides the option of using either a mouse-only or combined keyboard/mouse control scheme. Playing as both Holmes and Dr. Watson at times throughout the game, the immediate task is to figure out where the first attempted theft will occur, and the full demo reportedly offers several hours of gameplay.

The demo checks in at almost 650 MB, and can be found at the usual download sites such as FileFront and GamersHell, or directly from the game's original publisher, Focus Home Interactive.
