This is a very strange story, hard to explain. In Chicago, from time to time, in an almost predictable pattern, the ancient city of Byzantium/Constantinople/Istanbul appears. Hard to explain, but it sort of makes sense in the story. Certain people are licensed to cross over into the past, including the entrepreneur Mulreany, who trade modern trinkets for ancient baubles that he can sell on the artifact circuit. But competition is stiff between the traders, and many of the people of the old city are suspicious of visitors.
