Loreley

She was just another unhappy girl selling her body on the streets when John came into her life.

He told her that she carried the name of a feminine water spirit who lived on a rock on the eastern bank of the Rhine, Germany. He turned her into a strong and fearless woman, and taught her how to charm men. Every night he whispered passionate words in her ear as they made love on the rug in front of the fire.

When she was ready he sent her off to Vegas. Patrick Jane fell for her pathetic story hook, line, and sinker, promised to help her no matter what.

She said that Red John had killed her sister – she was an only child, actually – and she was after revenge exactly like him. She made him feel alive again after ten years' worth of self-denial and self-inflicted punishment. They spent six months on the run, sleeping together and supposedly devising a plan to catch their common enemy.

The poor wretch never saw it coming when the police caught him red-handed over the body of an alleged serial killer's minion – who was actually a harmless stranger she'd picked at random.

From the dark corner where she was hiding, Lorelei only smiled.
