Im a bit stuck. ive gotten the Bible, Sex Magazine. Electronic Card, The Tahitian Monkey and the Photograph of the Grave.
Have no idea what to do next
I'm as stuck as you are.
Spoiler
I've got the magazine, keycard which I used to get into where the doctor is, Bible, picture of tombstone which I looked at to see which grave to dig up to get the last remains of monkey stuff, chalk from where the coach was, not sure what thats for. I am getting lost quite a bit wandering from place to place but I guess we are now looking for some kind of lubricant to mix with the monkey remains.
I finished the game.
Spoiler
when you have the chalk, give it to the mafia guy and he will give you oil
