Salvage and Demolition is the other Tim Powers novella that I read in an afternoon or so last autumn. It’s a fun mashup of genres: It starts as a noir mystery with a splash of Bukowski and a studied bookishness; it veers [spoilers] into time travel and Lovecraft, with just a little bit of Snow Crash Sumerian.
Is the dame trouble? Of course she is. Should our hero have stayed sober? Almost certainly. Have the old dead gods gone mad? You know it. Does the Ace Double paperback hide the means for saving the world? That would be telling.
