"Bad Blood: Secrets and Lies in a Silicon Valley Startup" (Encore)

(Note: This show first aired early last year.) On this edition of StudioTulsa, we meet investigative journalist John Carreyrou, a two-time Pulitzer Prize-winning reporter with The Wall Street Journal. He broke the story of the fraud perpetrated by the medical tech company known as Theranos and its charismatic young CEO, Elizabeth Holmes. That story is the basis of his book, "Bad Blood," which he tells us about. At its peak, Theranos had a market value of $10 billion -- and its flawed prototype was actually in market-testing in both California and Arizona before Carreyrou helped expose the fraud.
