Short's body was discovered on January 15, 1947.
Ellroy is the best-selling crime writer of such novels as L.A. Confidential, Blood's a Rover, American Tabloid, and two memoirs, The Hilliker Curse and My Dark Places.
Ellroy is a larger-than-life character who was so emotionally wounded as a child when he secretly cursed his mother dead after an argument, and she turned up dead three months later. When his father gave him The Badge by Jack Webb, he was astonished after reading about the Black Dahlia. For him, the Black Dahlia was just like his mother -- and he became obsessed.
Wednesday's episode, "Dead Women Own Me," also features several other murders, including Ellroy's mother, Jean Hilliker (1958), 16 year old Stephanie Gorman (1965) and 17 year old Lily Burk (2009).
Ellroy is a lively host who enjoys alliteration. He also doesn't mince words. "Closure is nonsense," he insists. "Nothing this bad ever ends; murder is a powerfully perennial puzzle."
The show includes several interviews and a couple of scenes with "Barko," Ellroy's animated bull terrier sidekick.
