You probably haven't heard anything about this, but: Serial is back for Season 3. Stephanie Green is also back to discuss the first two episodes; the heralded podcast's less appealing qualities; and versions of S3's stories This American Life may have done better in the Most Wanted section.

As our Cold Case, we're looking at the rise and rise and fall of Theranos via John Carreyrou's outstanding bestseller, Bad Blood: Secrets and Lies in a Silicon Valley Startup. What's with Elizabeth Holmes's odd, affected voice? Which other con artists (Trump) and cults (Scientology) did the Theranos story remind us of? And can Carreyrou hurry up and write some more books? From the "mistake by the lake" to the city by the Bay, it's The Blotter Presents, Episode 70.
