Sir Arthur Conan Doyle: Memoirs of Sherlock Holmes

9. Adventure IX: The Greek Interpreter (continued)

"Excellent, Watson!" cried Holmes. "I really fancy that you are not far from the truth. You see that we hold all the cards, and we have only to fear some sudden act of violence on their part. If they give us time we must have them."

"But how can we find where this house lies?"

"Well, if our conjecture is correct and the girl's name is or was Sophy Kratides, we should have no difficulty in tracing her. That must be our main hope, for the brother is, of course, a complete stranger. It is clear that some time has elapsed since this Harold established these relations with the girl--some weeks, at any rate--since the brother in Greece has had time to hear of it and come across. If they have been living in the same place during this time, it is probable that we shall have some answer to Mycroft's advertisement."

We had reached our house in Baker Street while we had been talking. Holmes ascended the stair first, and as he opened the door of our room he gave a start of surprise. Looking over his shoulder, I was equally astonished. His brother Mycroft was sitting smoking in the arm-chair.

"Come in, Sherlock! Come in, sir," said he blandly, smiling at our surprised faces. "You don't expect such energy from me, do you, Sherlock? But somehow this case attracts me."

"How did you get here?"

"I passed you in a hansom."

"There has been some new development?"

"I had an answer to my advertisement."

"Ah!"

"Yes, it came within a few minutes of your leaving."

"And to what effect?"

Mycroft Holmes took out a sheet of paper.
