Query: A good summer suspense

I just finished this book in a whirlwind. It certainly was a page turner.The story is told from the point of view of Beck - a pediatrician whose beloved wife was murdered eight years before. Or was she? Recent events have led him - and the FBI, and the original people who paid for the killing - to question the official story.It is also the story of love - friendship love, companionship love, parental love, and spousal love.I really enjoyed this book. There is a bit of worldview attributed to the doc that you can tell is that of the author (how he looks at his patients, and their parents, is often a topic in the book). The casual back-story of his sister and her partner, and their trials as a couple, are told almost off-hand, and aren't of huge impact to the plot, but are, nonetheless, necessary to the story. They give you a fuller picture of the supporting cast than you usually get in the summer suspense.
