When will Sherlock Holmes: Nemesis be available in North America, you ask? Elementary, my dear gamers. The answer is "very soon", as The Adventure Company announced today that the great detective's newest mystery has now shipped to retailers.

In the fourth Holmes adventure from Frogwares, Sherlock finds himself up against perhaps his greatest (gaming) opponent yet. Famed French burglar Arsène Lupin, the fictional creation of Maurice LeBlanc, has challenged Holmes to a battle of wits, announcing his intention to deprive London of five precious artifacts in a week. It's up to Holmes, with the help of his able assistant Dr. Watson, to discover the object and location of each new theft, and prevent a great humiliation for Britain.

To help mark the occasion, a new trailer for Nemesis has also been released, showing a montage of in-game footage that includes several of the game's locations and even some of its puzzles. The 11 MB trailer can either be streamed or downloaded from sites like GamersHell or FileFront.
