Arsène who?

That may have been the question asked by many when Sherlock Holmes versus Arsène Lupin was released earlier this year, which perhaps explains why the newly-announced US and UK versions of the game will be known as Sherlock Holmes: Nemesis.

In the fourth Sherlock Holmes mystery from Frogwares, the great detective matches wits with Lupin, the fictional gentleman burglar created by French writer Maurice Leblanc. The young thief is in London at the start of his criminal career, and has threatened to steal five national treasures in five days from such historic locations as British Museum, the Tower of London, and Buckingham Palace unless Holmes can foil his plans.

Under its original title, the game has been available in mainland Europe and through commercial download for several months. The retitled Nemesis will be published by Focus Home and Ascaron in the UK, due out in the third quarter of this year, and an as-yet-unnamed publisher in North America.
