David Baldacci has written many best sellers and he knows exactly how to devise a plot and ratchet up the tension. Our two ex-Secret Service agents who are now PIs, just happen to see a frightened teenager out in a storm with a gun. They stop to help and are then intrigued enough by his story to get further involved. His Dad has been killed in Afghanistan but something doesn't add up. Uncovering the truth about a corrupt terrorist plot that goes right up to the White House will take all their skills and fighting abilities. Excellent.
