sherlock holmes vs lupin

HiMaG,Marion or...am at entrance to Museum...can click on lock but does not get any larger and so can enter
the combination..any idea what is keeping me from doing..have checked MaG's WT...(BOX)..thanks Chuck

Hi Chuck, if you don't get a close-up of the lock, it means that you have missed a step/trigger somewhere. Maybe restore to a previous save and follow the walkthrough closely up to this point to see what you have missed. It's probably just one little thing, but that's all it takes to prevent progress in the game.
