I'd read one Baldacci book a few years back (Last Man Standing, I think)and thought it was okay. Well-done, with good characters, although a bit dull. Which is why I was surprised that this one was so, well, bad. Not badly written, and it had interesting characters, but the characters just didn't make any sense together, and I could never keep them straight, or understanding his this bunch of goofballs could do the investigative work Baldacci attributes to them. It's an awful lot like "The A-Team" but with less interesting characters (and no van).
It's difficult to put my finger on what I didn't like - but I definitely didn't.
