“‘Yes, sir.’
“‘Then take the treaty and lock it up there. I shall give directions that you may remain behind when the others go, so that you may copy it at your leisure without fear of being overlooked. When you have finished, relock both the original and the draft in the desk, and hand them over to me personally to-morrow morning.’
“I took the papers and—”
“Excuse me an instant,” said Holmes. “Were you alone during this conversation?”
“Absolutely.”
“In a large room?”
“Thirty feet each way.”
“In the centre?”
“Yes, about it.”
“And speaking low?”
“My uncle’s voice is always remarkably low. I hardly spoke at all.”
“Thank you,” said Holmes, shutting his eyes; “pray go on.”
“I did exactly what he indicated, and waited until the other clerks had departed. One of them in my room, Charles Gorot, had some arrears of work to make up, so I left him there and went out to dine. When I returned he was gone. I was anxious to hurry my work, for I knew that Joseph—the Mr. Harrison whom you saw just now—was in town, and that he would travel down to Woking by the eleven o’clock train, and I wanted if possible to catch it.
“When I came to examine the treaty I saw at once that it was of such importance that my uncle had been guilty of no exaggeration in what he had said. Without going into details, I may say that it defined the position of Great Britain towards the Triple Alliance, and fore-shadowed the policy which this country would pursue in the event of the French fleet gaining a complete ascendancy over that of Italy in the Mediterranean. The questions treated in it were purely naval. At the end were the signatures of the high dignitaries who had signed it. I glanced my eyes over it, and then settled down to my task of copying.
