I am fairly sure I have the correct game. I am absolutely sure that in one of Frogwares' later Holmes games, the conclusion contains a framed picture of Holmes and a young girl who looks a great deal like him. I would like to have and be able to copy that picture for a small informational paper I'm writing, but have neither the time nor the inclination to replay the game through to the end just for the picture. Is there a chance that anyone on this site has a copy of that pic?

There is a simple solution for that, look at a video walkthrough and go to the end of the game.
Take a screenshot of that picture.

If it is for publication then you probally should ask permission from the maker of the videowalkthrough.

Thanks for an obvious idea that I would never have thought about. Ill try it. As to the permission, THAT I did think of and will absolutely seek it if the writing will in any way go public. Thanks for the help.
