What a brilliant novel. I will keep this short but suffice it to say, one of the best books I have read in many years, beautifully constructed.
The story is historical fiction centred on a fictional industrialist pre World War One, built around a spy/murder who-dun-it plot. What makes it brilliant is the construction where the book is really made up of three novels, each building on the same story but being told from completely different perspectives, each entertaining in its own right, and each giving a glimpse of more and more of the truth until everything is masterfully brought together in the very last chapter.
The descriptions of finance are fun and insightful, giving an insight into how important commerce and finance is in world events including countries going to war.
I also enjoyed the historical context, I knew little of the political history pre world war 1 with the rise of Bismarck and Germany and this was fascinating reading.
Thoroughly recommend reading for anyone who enjoys history, has a little background in finance or would like to learn more of that, and enjoys a spy type novel.
