This is the stranger-than-fiction story of Wirecard, once a $30 billion tech darling, now a smouldering wreck, by the journalist who brought it crashing down. When journalist Dan McCrum followed a tip to investigate the hot new tech company challenging Silicon Valley, everything about Wirecard looked a little too good to be true. In the space of a few short years, the company had come from nowhere to overtake industry giants like Commerzbank and Deutsche Bank on the stock market. As McCrum dug deeper, he encountered a story stranger and more dangerous than he ever imagined: a world of short sellers and whistleblowers, pornographers and private militias, hackers and spies. This is the astonishing true story of Wirecard's multi-billion-dollar fraud, Europe's biggest new tech darling revealed as a house of cards.
