The Increment by David Ignatius

4.0

When an Iranian scientist known only as "Dr. Ali" contacts the CIA with tantalizing information about Iran's covert nuclear program, the chief of Persia House, Harry Pappas, must decide if this is legitimate or an attempt by the Iranian government to dupe the United States. The White House is eager to act and divisions within the CIA ratchet up the urgency and intensity. Pappas reaches out to a British counterpart and friend who offers to assist in the form of a secret British spy team known as "The Increment." The reality of the situation is more complex than Pappas realizes and it soon becomes clear that he may need to betray his own country to learn the truth. The story moves between Iran, Europe, and the U.S., and leaves the reader guessing as the story unfolds. I felt the story was well-paced and found it to be a page-turner from start to finish. My only quibble is with one aspect of the ending that I felt wasn't as developed as it could have been (at least not to me), but it didn't detract from my overall enjoyment of the book. I used this for the 2017 PopSugar Ultimate Reading Challenge prompt "an espionage thriller."
