At the unveiling of a statue created in memory of three youths who sacrificed themselves to dispose of a bomb, two people who were snuck in to try and unveil a purported scam behind the story are found murdered inside the statue. Shinjuurou initially suspects the statue's commissioner, Hakuro Shimada, as the murderer, but Inga's question proves his innocence. After a brief depression and a pep talk from Kazamori, Shinjuurou deduces the culprit to be the statue's creator, Youko, who killed the men before they were transported, before later revealing the location of gold bricks that Hakuro had hidden.
