We'll be the first to admit that the Most Useful Podcast Ever doesn't pursue a lot of hard-hitting journalism, but that's ok, because this week's guest, Elaine Shannon, certainly does. She came upon the story of criminal mastermind Paul Leroux while tracking the drug trade in Afghanistan, and eventually wrote a book—Hunting LeRoux: The Inside Story of the DEA Takedown of a Criminal Genius and His Empire—with the help of the DEA agents who took him down (two of whom also joined us for this week's podcast). Also on this episode: Sinks and toilets, sawdust, and the Houston rodeo.  Learn more about your ad choices. Visit podcastchoices.com/adchoices
