In the french gallery where the two paintings are identical,I clicked on each one but can't get the magnifying lens on the painting at right to compare which is fake. It will only show up on the one at left to be examined even after Holmes says that they are identical. therefore,I can't find the letter I in the painting at left because it will not allow me to use the lamp? I can't figure out why this is so after repeately retracing my steps.

Jacky, with the magnifying glass, did you see Lupin in the left painting? Then use the lamp.

Edit: and you must get the commentary of Sherlock saying he needs the lamp.

Thanks, Chief.

Thanks for the tip chief. I did just that and it worked.
