The story - because it is one story, albeit with different, wholly engrossing episodes - begins in Berlin in 1933 with the arrival of a young Englishwoman, Clara Vine. A rather unsuccessful actress, she has heard that the film industry in Berlin is expanding, and, as this coincides with a wish to put a distance between herself and an unwanted suitor, she decides to try her luck.
She comes to the attention of Goebbels, the minister for propaganda who also has responsibility for the film industry. Through him she meets his wife, and through her the wives of the other men at the top of the Nazi Party - a potentially useful situation which is not lost on British intelligence. Clara, in short, becomes a spy at the heart of the Nazi war machine.
There’s so much to enjoy in these books. Clara is a fascinating character. Jane Thynne explores the elements of her upbringing and character which have led her to be a good spy: her reserve, her self-sufficiency, her ability to inhabit different personas, to hide behind a mask. She’s a subtle creation: she isn’t an expert in self-defence, she doesn’t get into fights: she survives on her instinct, her intelligence and her quick wits. She’s kind and loyal, and she is in some ways vulnerable. She’s a character you come to care for.
Each book centres on a mystery of some kind - a murder, a missing person, a plot that has to be uncovered. But all this is set very firmly in the context of Berlin in the years of the Nazi ascendancy. Clara is right at the centre of things, so through her Jane Thynne can tell us how they managed to coerce a whole population to go along with their awful creed: how they convinced the people that they were under threat from enemies within and without, and that the only chance of salvation was to trust in a charismatic leader. It makes chilling reading - more so now than when I first read the books a few years ago.
The research behind all this is formidable. Jane Thynne is immensely knowledgeable about life in Germany during this period: both the big historical events and the minutiae of everyday life, down to the name of a popular lipstick, the details of the food people ate, the cut of a uniform. She weaves actual incidents - the capture of two spies which almost destroyed the British intelligence operation in Europe, a plot to kidnap the Windsors, Eva Braun’s suicide attempts - into Clara’s story, and does this with such skill that it seems completely likely and natural.
I think she’s a really excellent writer. I’m astonished that no-one’s made the books into a TV series as yet, and it surprises me that they aren’t far better known.
