Sally's Got A Taser

We can live again. At birth, two critical cells are harvested from a child, and simultaneously, a LifeChip is implanted. This LifeChip records the individual's life, experiences, memories, and emotions. The cells are stored securely. Upon the person's death, the LifeChip is retrieved and uploaded into a clone, developed from one of the harvested cells. The second cell is later used to extend the person's life further.
Thus, we can live again, experiencing up to Three Lives. Beyond three, the process becomes unstable, leading to deformities and death if additional clones are created. Three Lives is the limit. A psychopath has decided to harvest LifeChips from living individuals, thereby halting the process. By killing and extracting the LifeChip, they rob the individual of their chance at another life. Sally, with a recent qualification as a Private Investigator, has little cash and an annoying ex-husband.
Despite this, she has landed a job. A job that connects her with a surly policeman, a bright young student, and ultimately, a murderer.
