Second-year Kasaba University student Nakata Seigi rescues a foreigner being harassed by drunks. Wavy blond hair, blue eyes, and clear skin. The man who speaks unfaltering Japanese is Richard, a very competent jeweler with customers both domestic and international.
Thanked by Richard for being a "hero of justice," Seigi hires Richard to valuate a memento from his late grandmother, a pink sapphire ring. Through Richard, the mystery hidden in the ring is eventually revealed...
So I investigated the incident by 
looking through old newspapers,
لذا تحرّيتُ بشأن الحادثة 
،عبر البحث في الجرائد القديمة
Deswegen hab ich in alten Zeitungen
den Sprung vor den Zug überprüft.
Así que investigué el incidente
en periódicos viejos,

en periódicos viejos,
Alors j’ai enquêté sur le suicide
dans de vieux journaux,
Quindi ho indagato su quel vecchio incidente
cercando sui giornali,
Então investiguei o
incidente em jornais antigos,
Поэтому я искал старые дела
во всех газетах,
