Query: No pay-off

I enjoyed the writing and I was quickly drawn into the story. I was eager to find out what happened, but I was very disappointed in how the mystery was solved. Perhaps Coben was particularly rushed or uninspired when he was writing the second half of this book. I stayed in it for the pay-off, but there was none.There is actually a scene that reads like an episode of Scooby-Doo, in which the answer to the biggest mystery, solved off-stage, is revealed to the culprit.I don't mind that the scary guy is Korean, but since people don't know his name, they (and therefore, the author) repeatedly refer to him only as "the Asian man." Gracious.I'm curious enough to read another Coben book because I enjoy the "my life isn't what I thought it was" premise, but I hope I won't be wasting my time.
