Sherlock Holmes Mysteries
Clearly a tie-in to the movie now playing in theaters, skimming through some of the screen shots in the iTunes App Store you get the impression that this is a cool game to play. Best of all, Sherlock Holmes Mysteries is only $0.99 meaning that if the game isn't what you expected, you're out less than the cost of a gourmet coffee!
I'm definitely going to check this game out over the weekend. For more information about Sherlock Holmes Mysteries, check out the iTunes Store.
