I`m playing Black Dahlia over again and i think i might help ya Goopsta
. I`m guessing that you`re looking for the last missing newspaper from the 8th murder so you can find out the order of symbols of the planets in the trance that the psychic (forgot her name) put you in? Well i had a problem with getting the missing newspaper (must be a bug or something, go figure) so i just looked at the walkthrough
and i just wrote down the order of the symbols which is: Saturn, Mars, Mercury, Venus, Sun, Moon, Jupiter, Earth and Thule. (if you have trouble refer to the book at the psychic parlor for the symbols of the planets and the numbers of the planets combined with the numbers from dates from the newspapers) I then went back to the parlor and went thru them. After you go thru the planets in your trance you just follow the rest of the story and you wont need the other missing evidence anymore.
