Sherlock Holmes has always been one of the greatest literary detectives. With the new Robert Downey Jr. movie fresh in everyone’s minds, it stands to reason that some developers wouldn’t mind capitalizing on the publicity to give their software that extra push. A few Sherlock Holmes products have hit the App Store recently, one even based on the feature film. Thankfully, this one is not. Instead, Sherlock Holmes: The Game Is Afoot is actually an interesting combination of hidden object game, spot the difference game and ebook reader. As individual elements they’re nothing special, but blended together they make for a pretty decent fare.
