I do feel the urge to point out that she never committed any crime....her clients were the ones who technically committed the crimes in revealing the information to her. Possession of such information isn't a crime...it's what she does with it that matters. Sherlock committed more of a crime in cracking the code...

Edit: Following my own logic...she does, but only once in revealing the cracked code to Moriarty. Look at the original portrayal of her though...she did indeed commit something similar in the form of blackmail.

Not really. The king THOUGHT she would blackmail him, but she was only holding onto the photos because she was afraid HE was going to do something to HER. She never wanted to hurt him at all, just wanted to go on with her life and marry the guy she loved and get everyone to leave her the heck alone.

She was up to absolutely nothing at all.
