An excerpt from my recreation of Jack the Ripper's diary in The Ripper's Wife:
I lulled her with kind words; I soothed her with sweet deeds. I wanted her to trust me; I needed it. It would make the horror when it came so much the sweeter! I wanted to see the hurt and betrayal in her eyes as she died! I wanted this to be sublime, an experience I would never forget! I wanted this whore to close her eyes in rapture, to submit to me like the most willing lover, the one she had dreamed of all her life but never found. I wanted her to expect delights, to dream of them, only to awaken to a nightmare in my arms that was all too real as I plunged the knife in and twisted it around.
