In the 1920s and ’30s, people gathered in darkened rooms to explore the paranormal through seances. They were motivated by grief, spiritual devotion, or a desire to be entertained. Beth A. Robertson resurrects the story of a small transnational group and their quest for objective knowledge of the supernatural, casting new light on how science, metaphysics, and the senses collided to inform gendered norms in this era.

Robertson draws back the curtain to reveal a world inhabited by researchers, spirits, and spiritual mediums. Representing themselves as masters of the senses, untainted by the effeminized subjectivity of the body, psychical researchers in Canada, the UK, and the US believed that they could use machines and empirical methods to transform the seance into a laboratory of the spirits and a transnational empirical project. However, mediums and ghostly subjects could and did challenge their claims to scientific expertise and authority.
