So I've now read three of the "Repairman Jack" novels.
Jack is one of those Masculine Hero types that permeate American pop lit: he's presented as a level headed nice guy, but his whole way of life contradicts that.
Jack does "repairs", meaning if say, you are a contractor who gets stiffed by Donald Trump and have no legal recourse, Jack will scam Trump to get you your money back.
Also, Jack lives "off the Grid", having no (real) Social Security number, Tax records, takes all his payments in cash, which he uses to guy guns or other ordinance, the rest he uses to buy Gold coins.
Yet he isn't an End of the Worlder, considers those people nuts.
Oh and he eats junk food and drinks beer all day, but can still handle himself in a fight, due to his daily exercises routine (not doubt copied from Doc Savage).
All this sounds like I hate the character and these books, but I actually enjoyed them quite a bit.
They have a "loosey goosey" quality to them, with the Bad Guys having their own problems as human beings, apart from whatever dastardly plan they are trying to undertake. Also, even though two of the protagonists in the three novels I've read are actively engaged with the Supernatural, they frequently have no better idea of what's going on than Jack, something I found refreshing.
Think I need to re-read The Keep, esp having recently seen the Michael Mann adaptation.
