Book 2 in the alternate universe Black Knight Agency series.
"In a world without the Knight Agency, Jane Doe never became Jane Browne. Instead of becoming an agent, she became the right hand of a criminal mastermind ruling most of the underworld of Great Britain. It all started with a hand in a wrong pocket and eventually led to the founding of the Black Knight Agency. On the way, this story features heists, fights, and many familiar faces in new surroundings."
