Seven years ago, “Paul Hardy” was found with his head smashed in. He recovered physically, but not mentally. After another accident, his wits come back and a few memories. Googling for the one name he remembers brings the NSA to his door. He goes on the run, causing the un­rav­el­ling of a coverup.

Efficient, well-plotted thriller in the paranoid vein. The plot is as risible as most such books, but no matter. Enjoy it for a few hours.
