What If - Cat and Mouse
It had started innocently enough. Maria Helena Grayson Wayne had taken a job with a small security firm and had quickly learned the ropes. She had to have something to pay the bills in this strange new world. Once she was settled in, she had what it took to get onto the team that tested firm's security systems by breaking in. At first Maria loved it. It was challenging and fun, but then it became way too easy. Uncle Bruce had trained her since the age of five and it showed.

Maria wanted more of a challenge and she found one.

She broke into higher security places and took small mementos for herself. Those small mementos turned into bigger things, but she didn't keep them for herself. There were so many people living on the streets of Gotham that needed help. Maria fenced the little trinkets she stole and used the money to give to the shelters and soup kitchens of Gotham.

Steal from the rich and give to the poor. She became a female Robin Hood clad in purple and black.

Tonight she was breaking into the offices of one of the richest men, after Bruce Wayne, in Gotham. There was a diamond the size of a fist he was keeping in the safe in there.

She was on the roof and working on disabling the security systems.
