Tell No One by Harlan Coben

Harlan Coben writes so many twists and turns into this thriller you can't help but wonder how he kept track of it all.  Like many mass market thrillers, there are a number of points in the book that give you reason to question a character's actions-- and all too often character's choices seemed forced, as if they were doing something merely because it fit into the author's thriller template.  The action centers around pediatrics Doctor David Beck.  Beck's life-long love was murdered eight years prior, but suddenly he starts getting cryptic messages with details that only she could know.  Is she really alive?  Why does she tell him, "They're watching-- tell no one?"  Beck abandons everything, including good reason, to follow the possibility that his Elizabeth is still alive and on the run after all this time.  The set-up is good, but I'd lost my suspension of disbelief by the end.  Trying to guess who really did it and why is like trying to guess who will win an election that's still out for bids-- it simply stops mattering after a while.  Similar to some David Baldacci and some John Grisham books-- it's a thrill ride with little substance.
