Bad Blood documents one of Silicon Valley's genuinely most spectacular corporate frauds, John Carreyrou, an investigative reporter whose dogged pursuit of the story for the Wall Street Journal faced sustained, genuinely aggressive legal intimidation from the company itself, tracing how Theranos, a blood-testing startup founded by Elizabeth Holmes, reached a peak valuation of roughly nine billion dollars and secured a board of directors filled with genuinely prominent political and business figures despite technology that fundamentally, persistently failed to work as claimed, promising to run comprehensive diagnostic tests from just a few drops of finger-pricked blood when the company's actual proprietary devices produced results so unreliable that Theranos was secretly running many tests on conventional laboratory equipment while publicly claiming its own revolutionary technology performed the analysis. Carreyrou builds his investigation around genuinely extensive interviews with former Theranos employees, many of whom describe a workplace culture of pervasive secrecy, surveillance, and retaliation against anyone who raised genuine safety or efficacy concerns about the technology, and the book traces the specific, mounting deceptions that allowed Theranos to continue attracting massive investment and eventually reach real patients whose actual medical care depended on test results the company's own internal data suggested were genuinely unreliable, building toward Carreyrou's own reporting that ultimately, after facing significant legal pressure, exposed the fraud and led to the company's complete collapse.
