Deadly Women is an American documentary television series focusing on true crime, specifically female killers. It first aired in 2005 on the Discovery Channel. It was originally based on a TV documentary film called Poisonous Women, which was released in 2003. Deadly Women started as a miniseries comprising three episodes: "Obsession", "Greed", and "Revenge". After a three-year hiatus, the show resumed production in 2008 and began airing on the Investigation Discovery channel as a regularly scheduled series. The series is produced in Australia by Beyond International.
A 52-minute-long TV film narrated by Marsha Crenshaw served as the basic pilot to Deadly Women. It covered four cases of women throughout history who committed murders using poison.
Each of the three original episodes covered cases of various groups of women who were united by the episode's central theme. These three episodes were narrated by Marsha Crenshaw.
Deadly Women resumed production of Season 2 in 2008, with slight changes. A new narrator, Lynnanne Zager, was introduced; and each episode began to feature three cases instead of four.
Note: This is the first season of the show to display the mugshots (or artist renditions if they lived before the days of modern photography) of the convicted women after each of their stories are told.
