A thoroughly enjoyable read. Do not cudgel your mind trying to solve it; it's not that kind of mystery novel. Just read it for the pleasure of it. The author evokes early Restoration England well while using modern language. He creates vivid characters and can make those who are meant to be very intelligent and formidable -- Dr. Wallis and John Thurloe in particular comes to mind -- really come across to the reader as bright minds to be reckoned with, a difficult feat. It is long, intricate and involved, so no discredit to the reader if the 'hidden fingerpost' referred to in fitzgerald's review is not apparent on the first read-through. The book is liberally interspersed with different period views on religion, statecraft, science, history and many other subjects, so there are generous helpings of food for thought along the way. Overall a very satisfying experience.
