With 48 minutes remaining before the train reaches the next station, Sherlock declares that William and he can find the murderer in time. Sherlock relies on the evidence at the scene, while William pursues a psychological profile of the killer.
The killer had to have been carrying
the weapon and the room key.
.لا بدّ أنّ القاتل كان يحمل سلاح الجريمة ومفتاح المقصورة معه
Der Täter hatte wohl die Tatwaffe
und den Schlüssel bei sich.
Il avait l’arme
et la clé du compartiment sur lui…
O assassino estava carregando
a arma e a chave do quarto.
