It was all Adam's fault, really. He was producing an album Annika was recording and was going to bring Richie in to play drums. Annika saw an Instagram video of Richie in advance and when she noticed his prominently-featured red beard she knew she was in trouble because she wanted to keep things professional. And anyway, she assumed he was married (he wasn't). The three met in Adam's basement studio-- Adam immediately went upstairs to grab something, leaving Annika and Richie alone, which she took as an opportunity to make a joke about Richie (not) being a serial killer. Thank goodness Richie responded by bringing up John List, cementing his knowledge of true crime, and this tolerance for the gruesome has proved crucial because little did he know he was in for a lifetime of murder shows before bed.
