The story is absolutely fascinating; the writing leaves something to be desired. This is not a book about torture vs non-torture, but about using intimidation/control vs a more friendly approach to interrogating terrorists. The author is working as an interrogator in Iraq, but his techniques are informed by work in criminal investigation in the US. The main plotline is about how this group of interrogators finally found Abu Musab al-Zarqawi, but a lot of interesting details about the war in Iraq are revealed along the way.
