I love Ed McBain, or Evan Hunter to use his real name. I've read nearly all of his 87th Precinct crime novels and to be honest, I have yet to read his equal in the police procedural genre. This guy has been writing for what seems like centuries and it just gets better.
If you like your cops smart and troubled, your crooks bent and dodgy, your women alluring and unobtainable (occasionally) then I'd recommend dipping your tootsies in the waters of the 87th Precinct.
These stories are from when cops were still cops - not scientists or college graduates - just hard men with the law behind them and a small monthly paycheck for their troubles.
The man turned me to crime, what can I say....
