Another adventure game of Infocom's that was not based on an original idea, Sherlock did not turn out as well as it should have. While there is lots of color and flavor provided by the incredibly descriptive prose of 19th century London, there isn't that much of a developing plot in this game. In addition, since you portray Doctor Watson, Holmes himself does very little, if anything, to solve the case, which dulls the Sherlock Holmes mythos and mysteriousness. A good portion of the game centers around the search for several similar objects, though this may be confusing for quite a while, since the reasons for doing so are not obvious until later in the game. While the game has an interesting ending, the lack of involvement by Holmes and the few interesting puzzles don't make Sherlock stand out among Infocom's other adventures.
