Sigrid Harald isn't a main villain. I'll have to explain the main story for you to get it:
Axel Johann that is about to go to uni. He's been suffering from amnesia for about 2 years now. He's been looking forward to uni for quite a while now and sees it as a chance to start anew. However, on the day that uni starts, his apartment gets raided by the police and is arrested.
He is arrested because unbeknownst to him, before he lost his memories, he was the heir to the biggest crime syndicate in Europe. And alongside his father, the two ran a whole command chain of crime. Their organisation was involved in 90% of the crime in Europe. Everything from the drugs trade to assassinations.
However Axel has no recollection of these memories, at first he thought it just was a misunderstanding. But as the court case began, Axel saw the solid evidence in front of him. He saw pictures of himself with people he didn't know in places he's never been to. As more evidence was presented to the jury, there were phone recordings, letters, fingerprints, DNA. All of them tying him down to the centre of almost all crime in Europe.
He was looking at life imprisonment, but the way before the jury was to deliver their verdict, Axel gets a plea deal from MI5. Although Axel and his father are not in control of the organisation anymore. The organisation was still active, it just has new leaders now. So the plea deal is that Axel must overcome his amnesia and help MI5 take down the organisation, in return he will walk free.
But Axel isn't just accepting the plea deal for the sake of escaping jail. He wants to find out how he lost his memory and what exactly happened to his father...
------------------------------
And this is where Sigrid comes into play. She is one of the board of directors of KANE. A target for MI5.
So she's one of the crime bosses of Europe, there'll be about 3 in the book I'm planning to write up.
