Sherlock and Watson both walk together while Sherlock describes to Watson the characteristics of his clever but lazy brother Mycroft. They meet with Mycroft and Mr Melas, who has a case for Sherlock to solve. Mr Melas describes the case to Sherlock
Mr Melas describes how he was kidnapped in a carriage and taken to an unknown location to translate Greek. The men that captured them were scary and had dangerous weapons.
When Mr Melas arrived at the location, he was given strict instructions to translate for the men and only say what they wanted him to. After a while, he started using Greek to ask questions on the back end of the questions he was supposed to ask. Because of this, He was able to learn about the man (Paul Kradites) who was sitting across from him.
Mr Melas was dismissed and paid a large sum with a warning that if he ever told anyone of what had happened, the men would find him and kill him. He ignored this advice and went to the police and Mycroft Holmes. Then, Sherlock was brought in to solve the case. Not long after Melas describing the events, he was once again kidnapped by the men and taken back to the house.
The 2 men, Mr Melas and Paul Kadrites were found by Sherlock, Mycroft and Watson in a room with burning coal. Paul was unfortunately found dead as he was already malnourished and injured however the men were still able to save Mr Melas before it was too late
The 2 men got away with Sophy but were later found stabbed and even though it was thought they stabbed each other, Sherlock believed that Sophy had killed them out of revenge.
