So good you'll leave your food behind
Wow. I just experienced a first. I got home, having just finished The Chalk Circle Man by Fred Vargas. I was thinking about the book, sorting my mail, getting settled when I realized I'd left a bag of produce on the train. So wrapped up was I in the book's conclusion that I just walked away from the fresh produce I had bought hours earlier. Damn it. The book's plot, involving a mysterious person who draws circles on Paris streets at night, was much less intriguing than its protagonist, the strange Commissaire Adamsberg. I like that Vargas made Adamsberg a detective with a winning track record whose triumphs come from instincts, not intellect. He doesn't even enjoy reading! Such a departure from most mystery series chief inspectors. I found his approach fascinating. Fascinating enough so that I left behind the figs I really wanted. Damn it.
So if you want to lose yourself in a book, might I suggest The Chalk Circle Man? Just check for all your belongings before you exit the train/plane/home, etc if you're reading at the same time.
