The Hanging Woman

The Hanging Woman was the eighth of the twelve ghosts imprisoned in the mansion of Dr. Plato Zorba.

Death
Virtually nothing is known about the Hanging Woman's life. Her appearance would suggest that she was executed for practicing witchcraft.

After Death
Following her death, the Hanging Woman's spirit remained on Earth, unable to move on due to unresolved issues. During Dr. Zorba's travels around the world, he met and captured the Hanging Woman and imprisoned her in his mansion.

When Dr. Zorba was murdered and became the twelfth ghost, Cyrus Zorba and his family moved into the mansion. The Hanging Woman and the other eleven ghosts presumably crossed over when Benjamin Rush died and became the thirteenth ghost.

Trivia

 * The opening of 13 Ghosts which shows the twelve ghosts states that the Hanging Woman is the eighth ghost. However, some posters of the film state that she is the ninth ghost.
 * It is unknown if the Hanging Woman was a witch in life.
