Did you ask her whether in leaving she met any one or saw any one loitering about Charles Street?"
"She saw no one but the constable."
"Well, you seem to have cross-examined her pretty thoroughly. What else have you done?"
"The clerk Gorot has been shadowed all these nine weeks, but without result. We can show nothing against him."
"Anything else?"
"Well, we have nothing else to go upon--no evidence of any kind."
"Have you formed a theory about how that bell rang?"
"Well, I must confess that it beats me. It was a cool hand, whoever it was, to go and give the alarm like that."
"Yes, it was queer thing to do. Many thanks to you for what you have told me. If I can put the man into your hands you shall hear from me. Come along, Watson."
"Where are we going to now?" I asked, as we left the office.
"We are now going to interview Lord Holdhurst, the cabinet minister and future premier of England."
We were fortunate in finding that Lord Holdhurst was still in his chambers in Downing Street, and on Holmes sending in his card we were instantly shown up. The statesman received us with that old-fashioned courtesy for which he is remarkable, and seated us on the two luxuriant lounges on either side of the fireplace. Standing on the rug between us, with his slight, tall figure, his sharp features, thoughtful face, and curling hair prematurely tinged with gray, he seemed to represent that not to common type, a nobleman who is in truth noble.
"Your name is very familiar to me, Mr. Holmes," said he, smiling. "And, of course, I cannot pretend to be ignorant of the object of your visit. There has only been one occurrence in these offices which could call for your attention. In whose interest are you acting, may I ask?"
"In that of Mr. Percy Phelps," answered Holmes.
"Ah, my unfortunate nephew! You can understand that our kinship makes it the more impossible for me to screen him in any way. I fear that the incident must have a very prejudicial effect upon his career."
"But if the document is found?"
"Ah, that, of course, would be different."
"I had one or two questions which I wished to ask you, Lord Holdhurst."
"I shall be happy to give you any information in my power."
"Was it in this room that you gave your instructions as to the copying of the document?"
"It was."
"Then you could hardly have been overheard?"
"It is out of the question."
"Did you ever mention to any one that it was your intention to give any one the treaty to be copied?"
"Never."
"You are certain of that?"
"Absolutely."
"Well, since you never said so, and Mr. Phelps never said so, and nobody else knew anything of the matter, then the thief's presence in the room was purely accidental. He saw his chance and he took it."
The statesman smiled. "You take me out of my province there," said he.
Holmes considered for a moment. "There is another very important point which I wish to discuss with you," said he. "You feared, as I understand, that very grave results might follow from the details of this treaty becoming known."
A shadow passed over the expressive face of the statesman. "Very grave results indeed."
"Any have they occurred?"
"Not yet."
"If the treaty had reached, let us say, the French or Russian Foreign Office, you would expect to hear of it?"
"I should," said Lord Holdhurst, with a wry face.
"Since nearly ten weeks have elapsed, then, and nothing has been heard, it is not unfair to suppose that for some reason the treaty has not reached them."
Lord Holdhurst shrugged his shoulders.
"We can hardly suppose, Mr. Holmes, that the thief took the treaty in order to frame it and hang it up."
"Perhaps he is waiting for a better price."
"If he waits a little longer he will get no price at all. The treaty will cease to be secret in a few months."
"That is most important," said Holmes. "Of course, it is a possible supposition that the thief has had a sudden illness--"
"An attack of brain-fever, for example?" asked the statesman, flashing a swift glance at him.
