London, 2007. It’s summer in the City: the economy is booming, profits are up and the stock market sits near record highs. But journalist Gil Peck is a lone voice worrying it can’t last. Deep in the plumbing of the financial system, he has noticed strange things happening which could threaten the whole economy. But nobody wants to hear it: not the politicians taking credit for an end to boom and bust, not the bankers pocketing vast bonuses, not even Gil’s bosses at the BBC, who think it’s irrelevant. When Gil gets a tip-off that a small northern bank has run out of money, everything changes. His report sparks the first run on a UK bank in 140 years. The next day, Marilyn Krol, a director of the Bank of England dies in an apparent suicide. For Gil, it’s personal. Marilyn was his lover: was his scoop connected to her suicide? Or is there something more sinister in her death?
