Gabriel Knight 3, the final installment in the Gabriel Knight series, is one of the best adventures I have ever played. And, yes, I am aware of its many shortcomings. They frankly don't matter when you are presented with the very best and most elaborate puzzle ever. Anyway, you are here for the walkthroughs and here are the two best by Just Adventure and Sierra Help. And if you are more into hints, well, there are always the excellent UHS GK3 hints.
