Picked up Killing Floor, the first of Lee Child's Jack Reacher books this week for 50p. I already had One Shot but hadn't read it yet, and also picked up The Hard Way and Bad Luck And Trouble for 50p.
Now, I don't have the seven or eight books between Killing Floor and One Shot (yet!) but I'm guessing that Reacher's leave-no-trail drifter nature is set up to make all the books sufficiently standalone. Can anybody tell me if that assumption is correct, or do I need to read in order (which will mean waiting till I find the others)?
