Summer 1939. Germany has invaded Czechoslovakia. Jews desperate to flee Nazi persecution queue outside embassies in Berlin in the hope of getting a visa, while sending their children on Kindertransport to Britain. In the UK, the IRA’s bombing campaign continues. Scientists in Europe and America are researching atomic fission, and also at the Cavendish Laboratory in Cambridge. It is a vulnerable, combustible time. This is the setting for Nucleus by Rory Clements, second in his trilogy of history professor and amateur spy, Tom Wilde. In the first book in the series, Corpus, Tom Wilde was more amateur detective than spy. In Nucleus, the stakes are higher, war is imminent, spies are everywhere and so are traitors. The problem is, they look like friends. Asked by none other than the US president Franklin D Roosevelt to be a ‘clear and unbiased voice’ for him on research at the Cavendish, Wilde is drawn into a world of American millionaires, a Hollywood actress, champagne, tennis parties and horseracing. And then one of the Cavendish physicists, a withdrawn, complicated genius due to move to the USA to work with Oppenheimer, is found drowned in the River Cam. Was he killed because he had unlocked the answer to converting atomic fission into a bomb capable of destroying a city?
Meanwhile, Wilde’s girlfriend and neighbour, Lydia Morris, goes to Berlin on a mercy mission to search for the disappeared eight-year old son of Jewish scientist, Eva Haas, now in England. Could Albert have been kidnapped by the Gestapo to put pressure on his mother? And who is the mysterious German, Baumgarten, who helps Eva and her uncle, physicist Arnold Lindberg, escape to Austria. Tom Wilde, a specialist on Francis Walsingham, spymaster to Queen Elizabeth I, is an interesting protagonist; at times reckless but capable of analysis and leaps of faith.
Corpus was a slow read, at times lightly plotted, but Nucleus an emotional rollercoaster that continues until the last page. Clements avidly recreates the atmosphere of Britain on the brink of war; a summer where parties abound, people approach life with a reckless abandonment, where fear and paranoia combine with a ‘let’s get on with it’ attitude. I enjoyed Corpus but Nucleus is better. The plot twists and turns with all disparate elements connected together by the end. This is a compelling read which I devoured on a plane, sitting up to read it while others slept around me.

It is 1936. The Spanish civil war is in full swing. A constitutional crisis looms as Edward VIII considers abdicating in order to marry the woman he loves. Corpus by Rory Clements starts in Berlin as a young Englishwoman slips away from a friend to deliver a secret package to an unnamed man. Soon after, Nancy Hereward is dead. It is Nancy’s death which makes Cambridge history professor Tom Wilde ask questions, awkward questions which lead him to uncover conspiracy, lies, and pre-war positioning by Stalin and Hitler.
Wilde makes an interesting amateur detective. For one, he is American with a different reading of human nature; he sits on the fence and observes. For another, he is a professor of history; he analyses and looks for proof rather than opinion. And third, he has a cool motorcycle that he uses to cross the fens and investigate isolated country houses. The story starts rather slowly as Clements fleshes out various groups involved without letting the reader know how these people are connected, and who is traitorous. There is one out-and-out baddie, another who looks like a baddie but possibly isn’t, and a journalist who may or not be a spy or a traitor. The reader’s confusion reflects Tom Wilde’s muddle as he and Nancy’s friend Lydia, both disillusioned with official efforts to explain Nancy’s death, unite to investigate. I particularly enjoyed the description of Cambridge in the 1930s, college life, the city and surrounding fens. The portrayal of Cambridge dons is rather polarised, they all seem to be either fascists or communists, reflecting the political jockeying that went on pre-war.
The plot features twist upon twist as Wilde, and the reader, doesn’t know who to trust: is that policeman really honest, or in the pay of the fascists or communists? Perhaps there is one twist too many as Clements manipulates history to fit his plotline. I have a few minor quibbles, knowing that this is the first book of a series. Some of the loose ends were tied off conveniently at the end with minimal or no explanation. The gold plot was lightly sketched and lacked significance. And the budding romance seemed rather one-sided.
A good read, not a great read, but it left me liking Tom Wilde and anticipating the next novel in this spy series.
