The narrative reveals that the residents were killed one by one in the order of the C Concert scale. The grandmother, emotionally shattered by her son's death, would leave her room every midnight carrying the Stradivarius violin as if it were a child. On the night in question, she breaks the instrument and falls from the window. It is disclosed that the culprit had taped an object to lure her toward the window, causing her fatal fall. This sequence of events highlights the tragic consequences of the murders and the grandmother's fragile mental state following the loss of her son.
