I was really looking forward to this book, since nearly all the books in the Thomas Kydd series have, like the previous one, been consistently excellent. Sadly, this one is a disappointment. Kydd and his friend Nicholas Renzi get involved with Robert Fulton’s work on the submarine, both undercover in France and in England. The largely factual history of Fulton’s experiments are interesting, but I wanted to see Kydd and Renzi develop further. This one just doesn’t move the series along.
