The Wings of the Kirin

A man is stabbed to death in Tokyo's Nihonbashi area. The victim staggers with the knife still in the wound for eight minutes before collapsing under the winged statues of two Kirin on the famous Nihonbashi bridge. The suspect, on the other hand, is now in coma, having fled the scene and been hit by a truck. On hearing this news, his girlfriend, Kaori Nakahara, insist that he is innocent. The case falls to Kyoichiro Kaga, a brilliant detective. Kaga realizes that behind this apparently open-and-shut case is a tangled web of mystery involving both victim and suspect, and their families. What was the victim thinking as he died? Will Kaga unravel the mystery at the heart of the case?
