What do you know, this does have a chapter two!

Amélie Lacroix used to be the Widowmaker. She's not, anymore. Talon is gone, and the threat is over. But few if any governments are really willing to forgive a known terrorist with dozens - no, hundreds - of kills under her belt, so coming in from the cold wasn't really an option.

But one has to make a living somehow. A lot of the same skills used to infiltrate for assassination work just as well for other kinds of infiltration, and Amélie always did have an eye for spotting value in art.
