Oh man, Ali, I like the way you think! Hannibal has the added bonus of 0 concience! And the crudeness of the denizens of a bar would really set him off. I pay to see his reaction to a hauked lugie on the floor.
I would want Louis and Angel from John Connolly's Parker series at my back. No one screws with those two. Plus they usually have a knife or a gun on them somewhere. Parker wouldn't be a bad friend to have in a pinch either.
Too much good taste around here, so all my picks have been taken.
But, that's OK. I was having a REALLY difficult time choosing between Hap Collins & Leonard Pine, Kenzie & Gennaro ( w/ Bubba Rugowski in tow, of course ... ) or Charlie Parker along with his pals Louis & Angel.
And, if it HAD to be just one single fella then I guess Repairman Jack might be a good choice. He may not be the absolute toughest of the lot, but he certainly does have a good knack for getting out of places & situations alive.
If I had only one choice, I'd have the bouncer on my side - specially if that Bouncer was Royston Blake (or Blakey as he's called, from Charlie Williams' Mangel trilogy). No thought, no indecision, no moralising. Just wading in there and cracking some swedes.
Maybe I'd like to have Guthrie's Pearce on my side, too. There's a hard man (ho ho!) if you need one.
