When Phil Klay's book Redeployment was delivered to my apartment a few months ago, I was about to take a long subway ride down the eighty or so blocks to Columbia. I took the book with me. It wasn’t a good idea after all, to open it up and read the title story on the 1 train — crushed into the railing, rattling southward in the dark tunnel. My throat had closed up by the time I hit my stop. When I emerged out into the sunlight from underground, Sgt. Price, the bluntly insightful narrator of “Redeployment,” walked up the stairs and out onto Broadway with me.
