The Locket was supposed to be the last step in evolution. Instead, it made death a form of entertainment.
It first arrived in England, toting scientific backing and a declaration of support from the prime minister. It made world news when he unbuttoned his shirt to reveal the heart-shaped contraption, glowing a pale blue just below his collarbone. The way he smiled beggared no disbelief. He was now immortal, if the shell he inhabited failed, then his characteristics would be immediately moved from that locket to a new shell, younger and healthy, factory made.
