Thursday 28th October 1982. Hammersmith Odeon, London. Iron Maiden are about to play in front of a sold-out crowd. This engagement is crucial for the band, who have just changed their lead singer and try to face the protests against their latest album, The Number of the Beast, accused with links to Satanism. A tragedy is round the corner: Liam and Rose, who belong to a Catholic sect, are also there, stuffed with enough explosive C4 to cause a terrible massacre. Six weeks before, a journalist called Luke Wilkinson, is found dead on the banks of the Thames. The first to arrive is Detective Andrew Briggs, who immediately recognises the corpse: they were best friends at school, and Luke's sister, Hannah, was once his girlfriend. Everything found at the scene leads to a suicide, but Andrew does not agree. He is gifted with extraordinary intuition, but because of his distraction at work, and due to his desire to become a professional singer, the case is assigned to another detective.Despite everything, Andrew decides to investigate on his own, but the deeper he digs, the more complicated the mosaic becomes.
