Daily Diary, August 24, 2022, Day 723: I listened to a https://shedunnitshow.com/knockknock/ podcast yesterday morning about how spiritualism (the belief that people could communicate with the dead) was used in Golden Age Detective Fiction. I highly recommend this particular episode, I found it fascinating.
