In the Nihonbashi district of Tokyo, a man is found dead beneath a statue of a Kirin, a Japanese mythic beast. That same night, a young man named Yashima is injured in a car accident while fleeing from the police, and he possesses the wallet of the murdered man. In this novel by the author of the Edgar Award nominee The Devotion of Suspect X, the connection isn't as obvious as it seems, and Detective Kyoichiro Kaga's investigation—his third, after Newcomer—takes him down dark roads to uncover what really happened.
