Detective Conan

Three months ago, 24-year-old Kaoru Sasamori, who hired Kogoro to investigate her boyfriend, fell down the stairs and died. At her funeral, Kaoru's brother accused her boyfriend Tsuge of pushing her down the stairs. In present day, Kogoro is summoned by Tsuge with the message, "Come and I'll tell you about her murderer". Kaoru's brother, her best friend Kazumi, and Tsuge's manager all show up at the same time. They find Tsuge bludgeoned to death in his workshop. Sleeping Kogoro explains that Tsuge was about to reveal Kazumi as the murderer through his shadow art. Kazumi, in love with Tsuge, killed Kaoru in hopes of being with him. She believed he was going to announce their relationship when she was summoned, but he instead told her to turn herself in. Blinded by rage, she kills him, but can't bring herself to destroy the incriminating sculpture as it was the only proof that Tsuge spent the last 3 months thinking about her.
