i cannot do the stained window puzzle,its driving me mad(there is a cheat. leadhead)but i don't know how to use it.anybody help.

Hi bigal,

To use the cheat codes for Black Dahlia:
Be in the close-up of a given puzzle and then just type in the letters on your keyboard;
You won't see them appear on-screen but the puzzle will be solved for you.

since i have solved the stained glass window problem i have tried to speak with louie been told that he's at the mission,talked to ernie,gone back to museum,but have no results from helen regarding the parchment sheets,all she wants to do is ask me if i want to look at the book again or the puzzle.i have got the photo from ernie,shown it to merylo,but am unable to speak to louie at any time.so now i cannot go any further please help.
