"I had never been in a printing shop before, so it was a shame that my first sight of one was ruined by all the blood. When I went down to the main room of the palazzo that morning, I was not anticipating murder, and I was certainly not thinking about ghosts. I was mostly contemplating the maps I had studied last night."
