When I first read Lawrence Block’s ‘Grifter’s Game,’ I had no idea what I was in for. The setup plays straight enough, but the ending – still, reading it through a second time – is one of the darkest things I’ve read, and that initial time through the book it was quite a leap from where it started. I loved it, but it was bleak stuff. On my second trip through, some years later, the themes are a lot clearer in the story, and the plummet not so steep, but it’s still a devastating read…
