Abby Yates was responsible for the book "Ghosts from Our Past Both Literally & Figuratively: The Study of the Paranormal", which she wrote along with Erin Gilbert and published it online without her permission. She and Jillian Holtzmann had teamed up after a falling out with Erin. When Erin discovered that the book she co-wrote with her had been released, she demanded that Abby take it down. During that conversation, Erin informed Abby about the paranormal sighting at Aldridge Mansion Museum. She agreed to take the book down from the internet if Erin took her and Jillian to the Museum and introduced them to Ed Mulgrave Jr.
While there, the three witnessed the appearance of the ghost of Gertrude Aldridge, although Erin got a little more than she bargained for as the ghost spewed slime all over her. Luckily Abby got the whole thing on video, which would later become viral on the internet, but was also the result of both Abby and Jillian being fired from from Kenneth P. Higgins Institute and Erin being fired from Columbia University.
