I just started The Black Dahlia, had it for a couple years and just found it again in the closet. I checked the walkthrough and it says the gun has a key in it, How do you find the key in the gun? I clicked everywhere and cant find it.This game reminds me of Tex games, with the video clips of real people.

Hi Catsmom....Bert's surely got the right approach here! Here's the description of how to do it from Peter Hart's walkthrough:

Then click on your case file, and click on and study the different aspects of it. Remember you can slide certain pages up & down. Next, examine your revolver; notice when you put the cursor over the butt/handle of the gun, it turns into the pointing arrow. Click here - HOLD - and pull forward to the barrel of the gun. ..
