Query: Dortmunder - underdone

I have enjoyed several of the Dortmunder books. This is just barely a Dortmunder book. Dortmunder is in it, but not much. If you know the Dortmunder gang, you might find some humor in the first half of the book. Otherwise, there are way too many new characters to make it interesting. When I finished the book, I felt cheated. My guess is that a young editor didn't feel confident enough to say to the money-making author: This is at best a first draft of the first two-thirds of a Dortmunder story that needs more Dortmunder.
