In an odd way this reminds me of all those English TV murder mysteries, like Inspector Morse, set in places like Oxford. They're well written, good characters, and the plots seem fairly plausible, but eventually it occurs to you that there were ten times as many murders investigated by that one detective as ever actually happened in Oxford. Here there's this one town, somewhat seedy, but not that big and in law-abiding Japan, and apparently there's a rape every ten minutes. I'm not complaining, works with the story. I like Inspector Morse too. I'm just saying.
