The decades-old disappearance of twenty-one-year-old teaching student Deirdre Duncan is the Holy Grail for true crime buffs—and Skylar Brennan, the host of the Ugly Town podcast, is no exception. In fact, on the mean streets of the internet, he’s considered an expert on the case. (In law enforcement circles, he’s viewed as just another crackpot internet sleuth.) Every February, the remote New Hampshire village of Woodlark is the site of a candlelight vigil for Deirdre. Family, friends, and “supporters” of the long missing girl, gather at the spot where she was last seen. This is Skylar’s first vigil, and his fans are excited, but maybe not as excited as the person who’s been anonymously emailing him coordinates to what this poison pen pal claims is Deirdre’s grave.
