Query: Good Premise Poorly Executed

Of the four Paul Lindsay books this is the weakest. It starts out well with the attempted recovery of a cache of masterpiece paintings stolen by the Nazis in WW2. There is some ingenous linkage with numbers on the frames to the location, but as the plot moves along it becomes more and more ridiculous with the mandatory romantic interest and wild shoot-em-ups. The ending is so preposterous that, unlike one review that said "it will leave readers gasping" it left this reader ready to throw up.
