This is World War Two historical fiction that is a blend of fact and fiction featuring the use of the occult by the Nazis to defeat Britain, spearheaded by Heinrich Himmler, with German spy rings supported by members of British aristocratic circles that want to see the rise of fascism. There are actual historical figures and events in the story, along with thinly veiled characters that represent real people from the era such as Intelligence chief Maxwell Knight. This is a story of the colourful world of music halls, magicians, seances, witches, spells, magic, mesmerists, memory men, spies and the infiltration of this world by the intelligence services. DS Ross Spooner, is a police officer, who has moved to work with MI5, recruited by The Chief to unearth British traitors and German spies entrenched in show business and occult circles with their plans to help the German war effort. Spooner is ideally placed to play this role, given that he grew up in an Aberdeen Antiquarian Bookshop, with a history of a personal interest in the occult and books on the subject.
A German spy, Karl Kohl, is parachuted into the Fens, but breaks his foot and is caught by locals. Kohl is interviewed by the security services, interested in mining him for crucial intelligence. They get more than they bargain for, learning of Clara Bauer, masquerading as a musical hall act under the name of Clara Brown. She is a powerful witch supplying German High Command with vital knowledge that orchestrates their accurate targeting of munitions and aircraft factories and more by the Luftwaffe, in the Birmingham Blitz. Spooner enters the world of showbiz to track down Clara and those close to her, such as Anna, Nils Anders, Nicolas Ralphe, and the powerful wealthy aristocrat, Simon De Vere, a feared man with his ancestral home of Hagley Hall. Spooner finds himself chasing down leads in Birmingham, Manchester and Portsmouth. He gets entangled with the subterfuge world of the occult as it seems Clara's murder is accessed by renowned medium, Helen Duncan at a seance. Is she for real or is she a fraud? Spooner finds himself sinking into the supernatural world of magic and spells, such as the hand of glory, encountering famous debunking Ghost Hunter, Harry Price, who has sold to De Vere the most famous grimoire in German history, once owned by Goethe. However, Spooner has not gone unnoticed by the enemy as danger begins to envelop him.
This is a fascinating historical novel that gives us insights on aspects of the Second World War that has often received little attention. Unsworth lets us know at the end that she has personal family connections to this history. She has engaged in some impressive research that has shaped the narrative, providing the bedrock for the compelling and gripping story that unfolds. There is much ambiguity as to the power and truth of the supernatural world, with the strong suggestion that it is not all to be disregarded. I really enjoyed reading this gripping piece of fact based historical fiction, finding it both entertaining and utterly absorbing. Many thanks to Serpent's Tail for an ARC.
