A former partner who vanished ten years ago suddenly reappears in the Butt Detective’s life, bringing an old connection straight into a new case. A mysterious message from Suisen leads to a counterfeit-art scheme whose reach extends far beyond one gallery or one city. With the art world facing a conspiracy large enough to destabilize collections across the globe, the investigation becomes personal. Solving the crime may require the detective to decide who from his past can still be trusted before he can identify who is manipulating the present.
