French Ambassador, there is the Russian, there is whoever might sell it to either of these, and there is Lord Holdhurst."
"Lord Holdhurst!"
"Well, it is just conceivable that a statesman might find himself in a position where he was not sorry to have such a document accidentally destroyed."
"Not a statesman with the honourable record of Lord Holdhurst."
"It is a possibility, and we cannot afford to disregard it. We shall see the noble lord to-day, and find out if he can tell us anything. Meanwhile, I have alredy set inquiries upon foot."
"Already?"
"Yes, I sent wires from Woking Station to every evening paper in London. This advertisement will appear in each of them."
He handed over a sheet torn from a note-book. On it was scribbled in pencil:—
"£10 Reward.—The number of the cab which dropped a fare at or about the door of the Foreign Office in Charles Street, at a quarter to ten in the evening of May 23rd. Apply 221B, Baker Street."
"You are confident that the thief came in a cab?"
"If not, there is no harm done. But if Mr. Phelps is correct in stating that there is no hiding-place either in the room or the corridors, then the person must have come from outside. If he came from outside on so wet a night, and yet left no trace of damp upon the linoleum which was examined within a few minutes of his passing, then it is exceedingly probable that he came in a cab. Yes, I think that we may safely deduce a cab."
"It sounds plausible."
"That is one of the clues of which I spoke. It may lead us to something. And then, of course, there is the bell—which is the most distinctive feature of the case. Why should the bell ring? Was it the thief that did it out of bravado? Or was it someone who was with the thief who did it in order to prevent the crime? Or was it an accident? Or was it———?" He sank back into the state of intense and silent thought from which he had emerged, but it seemed to me, accustomed as I was to his every mood, that some new possibility had dawned suddenly upon him.
It was twenty past three when we reached our terminus, and after a hasty luncheon at the buffet we pushed on at once to Scotland Yard. Holmes had already wired to Forbes, and we found him waiting to receive us: a small, foxy man, with a sharp but by no means amiable expression. He was decidedly frigid in his manner to us, especially when he heard the errand upon which we had come.
"I've heard of your methods before now, Mr. Holmes."
"I've heard of your methods before now, Mr. Holmes," said he, tartly. "You are ready enough to use all the information that the police can lay at your disposal, and then you try to finish the case yourself and bring discredit upon them."
"On the contrary," said Holmes; "out of my last fifty-three cases my name has only appeared in four, and the police have had all the credit in forty-nine. I don't blame you for not knowing this, for you are young and inexperienced; but if you wish to get on in your new duties you will work with me, and not against me."
