Miyako suspects her mother-in-law is a murderer. It's not just a case of them rubbing each other the wrong way--there is definitely something suspicious going on. But Miyako isn't exactly what she seems either. Her husband has no idea about her past life as a secret agent. When she decides to use her professional skills to investigate her mother-in-law, the delicate equilibrium of their lives is thrown wildly out of balance.Mixing mythology, family drama, corruption, and espionage, this is a gripping novella from the international bestselling author of Bullet Train. Paired with a second novella, Spin Monster, it explores the idea of progress, the power of close relationships, and the nature of conflict with deadly stakes.
