After being killed by my stalker, I found myself being reincarnated in a murder mystery novel I was reading right before I died. Instead of the heroine, I was reincarnated as the heroine's best friend Lilian Lemaire who dies early in the story from a serial killer who likes stalking and killing pretty young girls at night. Her death sets the beginning of a chain of murders. Victorian murder mystery!
