Christopher has been searching for "Verräter" for a couple of years. No one knows who he is or what he looks like, but Bang has gathered too much information about this person and knows that he is only dedicated to making big scams in high-end jewelry, like this time he stole a diamond necklace created by Cartier that is called “The Toussaint” and is said to have belonged to Liz Taylor and has been stored for decades in a security vault which was taken out for the MET gala that is held every year in New York in the art museum and that was where "Verräter" stole it without leaving traces of it or the necklace
