A well written, thoroughly readable novel, based on a real-life eighteenth century hoax. It's a great idea for a novel, that is equally well executed. The story focuses on Wolfgang von Kempelen, an ambitious civil servant in the Hapsburg Empire, who builds a 'chess machine' to impress the Empress. However, the 'machine' is really powered by an Italian dwarf named Tibor. As the fame of von Kempelen's invention spreads, the stakes become higher and the lengths to which he must go to protect his secret become greater.
What unfolds is a gripping thriller, intelligently written throughout, and with very well drawn characters. Both Tibor and von Kempelen are fascinating characters, as is Jakob, the Jewish carpenter who builds the 'chess machine'. There are some good supporting female characters too, in the shape of a scheming Viennese courtesan and a slightly unbalanced Hungarian baroness. I really cared about the characters and was emotionally involved in their story, which increased the drama and kept the pages turning.
Lohr shows a good understanding of human nature and interactions, and evokes the mood of the age and place very well. It's a well paced novel that keeps the reader guessing, and has a nicely written ending. He is equally at home writing scenes set in the Hapsburg court and lively scenes in local taverns, writing a tense emotional encounter or a rip-roaring rooftip chase.
I would recommend 'The Secrets of the Chess Machine' to most readers. It's a highly entertaining read but interesting with it, and one that the reader can become involved in. It mixes action with suspense, insight, sadness, humour and period drama, to make a well balanced book that is a plesure to read.
