Warning: This episode contains descriptions of violence against women. In 1942, wartime Melbourne lived under the dim, uneasy glow of the brownout; a city cloaked in half-darkness to hide from Japanese bombers. By day it bustled with soldiers, trams, and factory workers, but by night the familiar streets turned dark and silent. Within the shadows, crime escalated with one predator in particular. Three women were found strangled to death within days of each other. What was implemented for safety quickly became the advantage of a killer.
