“In answer to your advertisement of to-day’s date, I beg to inform you that I know the young lady in question very well. If you should care to call upon me I could give you some particulars as to her painful history. She is living at present at The Myrtles, Beckenham.

“Yours faithfully,

“J. DAVENPORT.

“He writes from Lower Brixton,” said Mycroft Holmes. “Do you not think that we might drive to him now, Sherlock, and learn these particulars?”

“My dear Mycroft, the brother’s life is more valuable than the sister’s story. I think we should call at Scotland Yard for Inspector Gregson and go straight out to Beckenham. We know that a man is being done to death, and every hour may be vital.”

“Better pick up Mr. Melas on our way,” I suggested. “We may need an interpreter.”

“Excellent,” said Sherlock Holmes. “Send the boy for a four-wheeler, and we shall be off at once.” He opened the table-drawer as he spoke, and I noticed that he slipped his revolver into his pocket. “Yes,” said he in answer to my glance, “I should say, from what we have heard, that we are dealing with a particularly dangerous gang.”

It was almost dark before we found ourselves in Pall Mall, at the rooms of Mr. Melas. A gentleman had just called for him, and he was gone.

“Can you tell me where?” asked Mycroft Holmes.

“I don’t know, sir,” answered the woman who had opened the door; “I only know that he drove away with the gentleman in a carriage.”

“Did the gentleman give a name?”

“No, sir.”

“He wasn’t a tall, handsome, dark young man?”

“Oh, no, sir. He was a little gentleman, with glasses, thin in the face, but very pleasant in his ways, for he was laughing all the time that he was talking.”

“Come along!” cried Sherlock Holmes abruptly. “This grows serious,” he observed as we drove to Scotland Yard. “These men have got hold of Melas again. He is a man of no physical courage, as they are well aware from their experience the other night. This villain was able to terrorize him the instant that he got into his presence. No doubt they want his professional services, but, having used him, they may be inclined to punish him for what they will regard as his treachery.”

Our hope was that, by taking train, we might get to Beckenham as soon as or sooner than the carriage. On reaching Scotland Yard, however, it was more than an hour before we could get Inspector Gregson and comply with the legal formalities which would enable us to enter the house. It was a quarter to ten before we reached London Bridge, and half past before alighted on the Beckenham platform. A drive of half a mile brought us to The Myrtles -a large, dark house standing back from the road in its own grounds. Here we dismissed our cab and made our way up the drive together.

“The windows are all dark,” remarked the inspector. “The house seems deserted.”

“Our birds are flown and the nest empty,” said Holmes.

“Why do you say so?”

“A carriage heavily loaded with luggage has passed out during the last hour.”

The inspector laughed. “I saw the wheel-tracks in the light of the gate-lamp, but where does the luggage come in?”

“You may have observed the same wheel-tracks going the other way. But the outward-bound ones were very much deeper - so much so that we can say for a certainty that there was a very considerable weight on the carriage.”

“You get a trifle beyond me there,” said the inspector, shrugging his shoulders. “It will not be an easy door to force, but we will try if we cannot make someone hear us.”

He hammered loudly at the knocker and pulled at the bell, but without any success. Holmes had slipped away, but he came back in a few minutes.
