Money isn't the only thing. It's the deadly thing.

After the murder of a high-flying executive in one of Tokyo's wealth management firms, Detective Hiroshi finds himself investigating the financial schemes that secure the money of Tokyo's elite investors. His forensic accounting gets sidetracked, though, by a second murder and the abduction of two girls from the home of a hotshot wealth manager.

The abducted girls are the daughters of an international couple who seemed to have it all—a large apartment in the high-end Azabu district, top schools for the children, and a life of happy affluence. Their life falls apart and they are swept up in threats and pursuits for reasons they cannot fathom.

Tracking the money and tracking the two daughters leads Hiroshi into Tokyo's murky financial past and outside Japan's borders as he discovers how overseas investments and tax shelters are really managed.

Hiroshi works with Sakaguchi and Takamatsu and others on the homicide team, including an assertive new detective, as they confront greed and violence in one of the wealthiest cities in the world.
