Query: One of De Mille's two weakest efforts

I absolutely LOVE Nelson De Mille and have read everything he has written, frequently several times. However, this book (and Mayday, which is offered as a special along with Cathedral and Charm School) are his two least interesting efforts. In my view, by a wide margin. De Mille's brilliant development of characters is nowhere in evidence in the book. Frankly, I found it to be both tedious and implausible. If you are a die hard De Mille fan, then I guess that you should go ahead and get this book to round out your familiarity with his catalog. But please don't make this the first book of his that you buy, because you might be dissuaded from buying his other titles. And that would be a crime. Start with Gold Coast or Plum Island, two of his absolute best, to get a true feel for what De Mille is capable of when he's at the top of his game.
