Metal poisons. Odorless ones. Toxic plants. Iocane powder, arsenic, old lace, poisons as self-defense, black mirrors, Aqua Tofanas, movie myths, and the start of testing for that which ails or kills you: we’ve got Historical Toxicology with Pulitzer Prize-winning science author & chemistry connoisseur Deborah Blum. She wrote the beloved “Poisoner's Handbook: Murder and the Birth of Forensic Medicine in Jazz Age New York” and takes us through a spooky walk in time, when chemistry was magic and homicide was an easier feat.

Are You A Charlotte?

Are You A Charlotte?

In 1997, actress Kristin Davis’ life was forever changed when she took on the role of Charlotte York in Sex and the City. As we watched Carrie, Samantha, Miranda and Charlotte navigate relationships in NYC, the show helped push once unacceptable conversation topics out of the shadows and altered the narrative around women and sex. We all saw ourselves in them as they searched for fulfillment in life, sex and friendships. Now, Kristin Davis wants to connect with you, the fans, and share untold stories and all the behind the scenes. Together, with Kristin and special guests, what will begin with Sex and the City will evolve into talks about themes that are still so relevant today. "Are you a Charlotte?" is much more than just rewatching this beloved show, it brings the past and the present together as we talk with heart, humor and of course some optimism.
