Yet none could solve 
the mystery of the locked room
لكن لم يستطع أحد حلّ لغز الغرفة المقفلة
Aber wir konnten das Rätsel um den
verschlossenen Raum nicht lösen
Pero nadie logró resolver
la habitación cerrada
Pero nadie logró resolver
la habitación cerrada
Le mystère de la pièce impénétrable
restant malgré tout entier,
Tuttavia, non riuscimmo a svelare il mistero
dietro gli omicidi avvenuti in quella camera chiusa,
Mesmo assim, como ninguém
resolveu o caso da sala trancada
Однако никто не смог раскрыть трюк
убийства в закрытой комнате…
