SummaryIn a bustling Ginza café, Kogawa Masao reunites with his enigmatic friend Touda Shintarou, a former prosecutor turned private detective known for his sharp intellect and disdain for women. Their casual debate about detective novels takes an unexpected turn when Touda reveals a cryptic letter from Aikawa Hiroko, a young woman pleading for help. Her father, a reclusive industrialist, lives in terror of anonymous threats marked by a sinister red triangular seal. Intrigued, Touda agrees to meet Hiroko, whose poised demeanor belies her desperation. \nAs she recounts her father’s unraveling sanity and eerie letters warning of impending doom, a chilling delivery arrives—another triangle-stamped message demanding her immediate return home. The tension escalates when a mysterious phone call threatens Touda to abandon the case. With Hiroko’s family secrets shrouded in fear and an unseen adversary watching their every move, Kogawa and Touda are drawn into a shadowy game of wits. The detectives’ resolve is tested as they confront a threat that blurs the line between paranoia and peril, leaving readers questioning who—or what—lurks behind the crimson seal.
