For the first time, you can see where it all began. The entire line of Sherlock GNAs takes place after the famed dive off of Reichenbach Falls, where Sherlock and Moriarty allegedly plunged to their deaths. Now you can see what happened after those incredible events, and how Sherlock got back in the investigatory saddle, through the eyes of his trusted friend, Dr. Watson.

Sherlock trusts you to prove your deductive prowess and solve cases that have left Inspector Lestrade, and Scotland Yard, puzzled to say the least. Be careful though, not only are your investigations perilous, but Sherlock himself has little tolerance for failure. However you choose to go about solving the mysteries, as always, it's your story, your choices, and your adventure.

At Baker Street, Sherlock Holmes is in turmoil since the news brought by Scotland Yard: the great novelist Ames Douglas has been poisoned! Everything seems to indicate suicide, but a note with a coded message persuades the famous detective to the contrary ...

Step into the shoes of Dr. Watson and lead the investigation alongside Sherlock Holmes: decide what to look for, pick up the clues and discover the meaning of this coded message, which will lead to the culprit!

Sherlock Holmes is a comic combined with a game, one title in a series subtitled "The comic in which you are the hero". You embody a character in a immersive story in which your choices guide your progress. You have a character sheet akin to those used in role-playing games that tracks your possessions, your special abilities, your coins, and your victory points. In general, gameplay consists in following the comic's panels — which contain clues, riddles and traps — and making choices about where to go and what to do, while using your visual perception to collect clues and be smart enough to resolve the riddles. As in any game, you can lose — sometimes really badly!
