Home by Harlan Coben

Ten years after a pair of children were kidnapped, a possible lead pops up in London. Windsor Horne Lockwood III, Win, spots Patrick Moore, one of the missing boys, (the other is his nephew Rhys Baldwin) being exploited on the mean streets of England. He calls on his best friend and past partner, Myron Bolitar to help him rescue the boy. But even though the boy is returned to his family, questions still linger about the other child, no age sixteen. While Win follows leads in Europe, Myron travels back to the scene of the crime to go over the events of that faithful day. But nothing adds up.

Follow the clues in this international thriller that twist and turns on the page, to its surprising end. The story moves light greased lightning right up to the satisfying ending.
