Arthur Brand is an art sleuth based in Amsterdam.
His clients ask him to find stolen works of art, and to find out whether a painting or sculpture being sold on the black market is the real thing.
One day, he received an email with an image attached of two gigantic horse sculptures.
The unknown owner of these statues was claiming that they had once belonged to Adolf Hitler and had stood outside his chancellery building in Berlin.
This led Arthur into a murky world of black market art dealers, billionaire collectors, and Neo-Nazis.
