Bob put me on to Mike Carey's Felix Castor books which, although not as well-crafted as Ben Aaronovitch nor as much fun as Jim Butcher's Dresden, are a good read and get better as they go along.
Is that the same Ben Aaronovitch who wrote a couple Doctor Who
stories in the late-1980s? What did he write? (I might give him a look, since "Remembrance of the Daleks" & "Battlefield" were the only two Sylvester McCoy stories that were really worth a damn.)
