The death of Roberto 'God's Banker' Calvi, found hanging from scaffolding under Blackfriars Bridge days before his bank’s collapse, lies at the centre of one of the most extraordinary criminal puzzles of all time. Straight from the dark heart of Italy, the story involves the largest bankruptcy in European history, complex forensics, and secret masonic rituals, with a cast of characters to put The Da Vinci Code to shame – including Opus Dei, the mafia, the Vatican and the governments of Italy, the USA and the UK.
