I have indeed, just to refresh (sorry not sure how to insert the spoiler tags, no forum controls showing up for me, so anyone reading can consider it a SPOILER)
I've just gotten the cell phone from the shop keeper and been to that apartment, cracked the safe ect.
I've unlocked the feder square section on the tube map with the information from the safe, but can't go to it on the first night (which I'm on)
I'm currently holding 405 euros, and have the dream ladies card (rang them) necklace, screwdriver, bear and power cord (and some other things of course, but I think that's all that's relevant)
So I have spoken to dr Mulkin, even gave him the pen, I think I've shown him everything. I got the name of the person from him that you can then go and 'google' in the internet cafe, but I didn't see any information there that moved me forward.
