“In which neighborhood?" I asked.

"The neighborhood of Mapstack-the Met's internal version of the Interpol's big data exchange system. It's usually worth a look, just for laughs. These people have no idea how the world works-how the little details connect up. They try to draw links between crimes, but they only work in straight lines so they miss it. They miss everything but fucking methodology. Like the real criminals-I mean, the ones who are so big you never even see them-can't vary their repertoire.”
