Query: Decent book, but had its shortcomings.

After Davis's previous book, The Plutonium Murders, became one of my all time favorites, I expected a bit more. I found plot of The Doomsday Kiss to be excessively complicated, and the book was so layered with scientific jargon that a true understanding of the plot was difficult to obtain. However, I did find the close escapes of Dr. Seacourt and the international espionage to be fascinating. Were this turned into a movie, I would not hesitate to go see it.And the grammar, I might add, was far better than in The Plutonium Murders. I noticed few mistakes in this book. Those few are forgivable, for to err is human.
