A London watch-maker named Joe has a lot of fun saving the world from a villain wishing to destroy it, while the British secret services are unknowingly assisting the villain. A fun book to read, absolutely. The one part I found annoying is that the villain is supposed to use an invention by a scientist who invented some sort of a universal truth machine hoping that if everybody will always know the truth this will prevent wars and other abuses. There is a bit of anti-science bias there, I thought. Again though, a totally enjoyable book.
