The K Apartments for Ladies in Tokyo conceals a sinister past behind each door; a woman who has buried a child; a scavenger driven mad by ill-health; a wife mysteriously guarding her late husband’s manuscripts; a talented violinist tortured by her own guilt. The master key, which opens the door to all 150 rooms, links their tangled stories.
