I am playing Black Dahlia and have resorted to several walkthroughs but am still having problems finding Louie at the Raven club. Any help would be gratefully received.
In order to get Louie to show up at the Raven club you need to try and call him from the bar first. I am being careful not to release too much info as I don't want to spoil it for you.
Gemma, I'm surprised nobody made mention of this sooner, as great a game as Black Dahlia is, it needs to be patched. Since you're still early in the game I'd recommend you download it and install it ASAP as it's likely only a matter of time before you hit a glitch that the patch will fix. You can get it from here
