Inspector Kenmochi the Murderer File 4 - S1-E22
Stupidity: The denouement in this episode does not make any sense. Two characters (the lawyer, the victim's sister) are suddenly present on the scene for the climax, but they were never invited and if they were at the hospital in the corridor right at that moment, Busujima could not sneak by Kenmochi's room. Later Kindaichi gingerly explains the rest at the other crime scene, which is in a different building somewhere else in the city - and they are all physically there, even the patients in their hospital gowns and slippers, it's not a dramatic rendition.
