"Who is there?" cried a gruff voice from within.

"It is I, McMurdo. You surely know my knock by this time."

There was a grumbling sound and a clanking and jarring of keys. The door swung heavily back, and a short, deep-chested man stood in the opening, with the yellow light of the lantern shining upon his protruded face and twinkling, distrustful eyes.

"That you, Mr. Thaddeus? But who are the others? I had no orders about them from the master."

"No, McMurdo? You surprise me! I told my brother last night that I should bring some friends."

"He hain't been out o' his rooms to-day, Mr. Thaddeus, and I have no orders. You know very well that I must stick to regula– tions. I can let you in, but your friends they must just stop where they are."

This was an unexpected obstacle. Thaddeus Sholto looked about him in a perplexed and helpless manner.

"This is too bad of you, McMurdo!" he said. "If I guarantee them, that is enough for you. There is the young lady, too. She cannot wait on the pubiic road at this hour."

"Very sorry, Mr. Thaddeus," said the porter inexorably. "Folk may be friends o' yours, and yet no friend o' the master's. He pays me well to do my duty, and my duty I'll do. I don't know none o' your friends."

"Oh, yes you do, McMurdo," cried Sherlock Holmes ge– nially. "I don't think you can have forgotten me. Don't you remember that amateur who fought three rounds with you at Alison's rooms on the night of your benefit four years back?"

"Not Mr. Sherlock Holmes!" roared the prize-fighter. "God's truth! how could I have mistook you? If instead o' standin' there so quiet you had just stepped up and given me that cross-hit of yours under the jaw, I'd ha' known you without a question. Ah, you're one that has wasted your gifts, you have! You might have aimed high, if you had joined the fancy."
