" You could loosely describe it as "Neverwhere meets Ed McBain meets Dresden Files" but it's its own thing. What I like most about it is the incredibly strong setting -- the chase scenes go down specific London streets past specific shops, the characters speak in specific London dialects using specific London slang (at one point a ghost speaks in specific *period* London slang), the cop follows specific london-cop police procedures, etc. It's just really professionally researched in a way I haven't seen before in other "urban fantasy."
