Query: They ought to be ashamed

This book is so much weaker than every other book in the series, that it could have been written by a different author. When I checked some other reviews, I found that, indeed, it is quite possible that it WAS written by a different author. I liked the other Karp novels; this is junk.There are endless preposterous coincidences. The plot is convoluted. It's just not a good book.
