It was 1992, and I had been renting her apartment in Prague for about a year. I had gone to the former Eastern Bloc shortly after graduate school on a United States government fellowship, and I felt it my duty to show by example how the free world worked. I thought I had been a model tenant. I kept the place neat, I paid my rent faithfully, I even made sure to put out fresh flowers when I knew she was coming over.

But that was the problem: I didn't always know she was coming over. She used to come in when I wasn't home, on tips from the neighbors.
