Searching for the true killer of Count Drebber, Sherlock and John set a trap for the culprit using a wedding ring found at the murder scene as bait. After a struggle in which the ring is lost, Sherlock is able to deduce who the real killer is.
Wait, does that mean you already
know who the true culprit is?
لحظة، هل يعني هذا أنك تعرف من المجرم سلفا؟
Sie haben doch nicht etwa schon
die Identität des Mörders …
Espera, ¿significa que ya sabes
quién es el culpable?
Tu sais déjà qui est le meurtrier ?
Espere, quer dizer que já
sabe quem é o culpado?
Ты... уже вычислил, кто убийца?
