Saikawa and Nishinosono return to the camp, putting off trying to find a solution to the case. But they can't stop thinking about it. They go back to the lab and investigate Dr. Shiki's rooms again, where they find a strange number that is a clue.
If her body's found next week...
...إن تم العثور على جثتها في الأسبوع القادم
Wenn ihre Leiche nächste

Si se descubre su cadáver 
la próxima semana...
Si son corps n’était découvert
que la semaine prochaine…
Se il cadavere della signorina Magata
fosse scoperto la settimana prossima...
Se o cadáver da Dra. Magata for 
descoberto só na semana que vem...
