Kinue Nomura survived World War II only to be murdered in Tokyo, her severed limbs discovered in a room locked from the inside. Gone is the part of her that bore one of the most beautiful full-body tattoos ever rendered.
 
Kenzo Matsushita, a young doctor who was first to discover the crime scene, feels compelled to assist his detective brother, who is in charge of the case. But Kenzo has a secret: he was Kinue's lover, and soon his involvement in the investigation becomes as twisted and complex as the writhing snakes that once adorned Kinue's torso.
