This article explores the articulation of the crime scene as a distinct space of theory and practice in the early twentieth century. In particular it focuses on the evidentiary hopes invested in what would at first seem an unpromising forensic object: dust. Ubiquitous and, to the uninitiated, characterless, dust nevertheless featured as an exemplary object of cutting-edge forensic analysis in two contemporary domains: writings of criminologists and works of detective fiction. The article considers how in these texts dust came to mark the furthest reach of a new forensic capacity they were promoting, one that drew freely upon the imagination to invest crime scene traces with meaning.

This article reassesses the role of gender in early modern demonic possession from a medical perspective. It takes as its starting point the demoniac Richard Mainy, who in 1585 claimed to be suffering from hysteria. Best known for its influence on Shakespeare's , Mainy's gender-crossing diagnosis should be read in the context of the close historical relationship between hysteria and epilepsy. While medical historians have viewed hysteria as the key possession-related illness, epilepsy was equally important. Both were seen as convulsive illnesses caused by an excess of reproductive fluids. Emphasizing the similarities rather than the differences between male and female sexuality, this shared etiology underpinned medical approaches to demonic possession.
