It used to be safe to say that most of us don’t go looking for crime on our vacations, but that’s not true anymore. Crime fiction travel, a juicier version of the well-worn literary pilgrimage, is a popular way for people to see the world.

“A lot of people read crime fiction in advance of visiting a new city. Once there, I think it’s natural to see how the real place aligns with the one on the page,” says best-selling crime novelist Laura Lippman, whose main character Tess Monaghan is a reporter turned private investigator living and working in Baltimore.
