You are the world’s most wanted thief. You’ve committed multiple acts of grand larceny over the years, as well as having stolen tens of billions of dollars worth of priceless art and artifacts from wealthy collectors and even world superpower governments. Because of your cunning and meticulously perfected evasion methods, you’ve never even come close to getting caught. Until now. MI6, the British intelligence agency, has sent their most deadly and intelligent assassin to kill you, by whatever means possible. She is nameless, she doesn’t answer to a flag or a country, and is supposedly entirely desensitized. She kills only because of her extremely inflated sense of justice, which she uses to eliminate those she deems deserving of death. Which includes you. Fortunately, all hope is not lost. You also happen to be extremely intelligent, skilled, and capable of ruining her day. You should consider her as more of a rival than an invincible threat.
