There is a black sheep in every family, but –what happens when a white sheep is born in of a family of black sheep? I will explain it to you, if you please: I'm Linus Filstrup, an honest boy who has nothing to do with Arlo, my twin brother, who is a real hooligan and the pride and joy of the Filstrups, a family of proper thieves and swindlers. I was getting by in high school, until the disastrous day when I stood accused of having stolen a large sum of money. So, I had to start investigating to unmask the real culprit, clear my name and... let my family down again!
