The shop is called Outland, it's the Norwegian equivalent of SFBok in Sweden, but with quite a few shops around the country (all the largest cities and a few smaller ones). I know the guy responsible for events at the Oslo shop, so i keep up with what's happening there.
Yes, that sounds like a great fit. There was a swedish game called Noir 10-15 years ago that had a setting with some supernatural almost horror elements woven into an early 20th century type metropolis. I enjoyed that setting a lot (not so much the rules after a while) and was thinking of taking some inspiration from that setting for my con scenario.
