وكانت طالبة بيانو متوترة تنتظر دورها. كان Vadim، المدير، قد أخبر المعلمين بعد ظهر ذلك اليوم أن المدرسة لن تستطيع في العام القادم الإبقاء إلا على واحد منهم – وأنه اتخذ قراره بالفعل. وخلال الاستراحة عُثر عليه ميتًا في غرفة الإيقاع، بجانب طبل التيمباني. كان خمسة أشخاص قريبين منه، وأدلى كل منهم بإفادة قصيرة واحدة – جد الشخص الذي كان وحده معه.","rules":{"standard":["يحتوي كل <b>صف</b> وكل
