Detective Conan (1996)

Season 1: Episode 650

Conan declares Mitsui is innocent since she was witnessed leaving Miku's room; Sawaguri inferred the culprit crossed over from the balcony and left by his room. As for Miku's death, Conan explains she was mimicking the suicide of the main character in her book. Sawaguri becomes distraught as a result and is taken in by the authorities. Later, Conan reveals his previous deduction was a bluff and that Miku was murdered by Yuchi, due to the fact Mitsui left the room with Yuchi's slippers revealing Yuchi was still in Miku's room after she left. As evidence, Yuchi's book reveals it had been sandpapered to clean off Miku's blood. Yuchi confesses and reveals Miku took all the credit on the book they collaborated on motivating her for revenge.
