My Review
Divination is a novella that acts as an introduction to the author’s historical mystery series featuring Dr. John Dee, mathematician, astrologer and Fellow of Trinity College, Cambridge. The series encompasses the reigns of King Edward VI to Queen Mary, a very turbulent period in English history. A perfect setting then for a historical crime mystery!
Although a real historical figure, in Divination John Dee is cast in the role of investigator as he seeks to find the person responsible for the murder of Polish astronomer, Mikolaj Kopernik. Working out the motivation for the murder is probably his easiest task because Kopernik had claimed his astrological calculations indicated a threat to the peace of the realm. But from whom? That’s the task Dee is given, requiring him to try to replicate Kopernik’s intricate calculations based on his scribbled manuscripts. And there’s pressure for him to do it quickly. Fortunately, Dee is a mathematical mastermind. Unfortunately, there are people who will do anything to prevent details of their plan being discovered, placing Dee’s life at risk.
Although taken under the wing of an influential figure, Dee soon discovers the Tudor court is a place of intrigue, espionage and competing factions. Prime amongst these is the rivalry between the man appointed Lord Protector to the young King, Edward Seymour, and his brother Thomas Seymour, a man who believes he has been overlooked.
The story builds to a dramatic conclusion. Along the way, Dee proves quite capable of a spot of deception himself, including one that comes with side benefits!
Divination is a well-crafted and enjoyable historical mystery that will appeal to fans of C. J. Sansom’s Shardlake series. The good news is you can get another free novella featuring John Dee – Speculation – by signing up for the author’s newsletter here. An excellent way to get a taster before you embark on the whole series.
