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.
He's not like us; he won't stop

.ليس مثلنا، لن يقوم بالمستحيل لينال مبتغاه

qualquer coisa para conseguir o que quer.
Мы считаем, что цель оправдывает средства,
 но он не такой.
