To cross the street in either direction on Nevsky Prospect -- one of the main streets in St. Petersburg -- you need to go into this pedestrian underpass. When we did so, on a bright spring afternoon (our wedding anniversary), my camera was stolen. I'd just entered the underpass, and as my eyes adjusted to the gloom someone bumped into me quite hard, and I knew my camera was gone when my left shoulder suddenly didn't feel the weight. But there was a crowd, and no obvious villan.
