"No; they are very few."
"And a curve, too. Points, and a curve. By Jove! if it were only so."
"What is it, Mr. Holmes? Have you a clue?"
"An idea--an indication, no more. But the case certainly grows in interest. Unique, perfectly unique, and yet why not? I do not see any indications of bleeding on the line."
"There were hardly any."
"But I understand that there was a considerable wound."
"The bone was crushed, but there was no great external injury."
"And yet one would have expected some bleeding. Would it be possible for me to inspect the train which contained the passenger who heard the thud of a fall in the fog?"
"I fear not, Mr. Holmes. The train has been broken up before now, and the carriages redistributed."
"I can assure you, Mr. Holmes," said Lestrade, "that every carriage has been carefully examined. I saw to it myself."
It was one of my friend's most obvious weaknesses that he was impatient with less alert intelligences than his own.
"Very likely," said he, turning away. "As it happens, it was not the carriages which I desired to examine. Watson, we have done all we can here. We need not trouble you any further, Mr. Lestrade. I think our investigations must now carry us to Woolwich."
At London Bridge, Holmes wrote a telegram to his brother, which he handed to me before dispatching it. It ran thus:
See some light in the darkness, but it may possibly flicker out. Meanwhile, please send by messenger, to await return at Baker Street, a complete list of all foreign spies or international agents known to be in England, with full address.
Sherlock.
"That should be helpful, Watson," he remarked as we took our seats in the Woolwich train. "We certainly owe Brother Mycroft a debt for having introduced us to what promises to be a really very remarkable case."
His eager face still wore that expression of intense and high-strung energy, which showed me that some novel and suggestive circumstance had opened up a stimulating line of thought. See the foxhound with hanging ears and drooping tail as it lolls about the kennels, and compare it with the same hound as, with gleaming eyes and straining muscles, it runs upon a breast-high scent--such was the change in Holmes since the morning. He was a different man from the limp and lounging figure in the mouse-coloured dressing-gown who had prowled so restlessly only a few hours before round the fog-girt room.
"There is material here. There is scope," said he. "I am dull indeed not to have understood its possibilities."
"Even now they are dark to me."
"The end is dark to me also, but I have hold of one idea which may lead us far. The man met his death elsewhere, and his body was on the ROOF of a carriage."
"On the roof!"
"Remarkable, is it not? But consider the facts. Is it a coincidence that it is found at the very point where the train pitches and sways as it comes round on the points? Is not that the place where an object upon the roof might be expected to fall off? The points would affect no object inside the train. Either the body fell from the roof, or a very curious coincidence has occurred. But now consider the question of the blood. Of course, there was no bleeding on the line if the body had bled elsewhere. Each fact is suggestive in itself. Together they have a cumulative force."
"And the ticket, too!" I cried.
"Exactly. We could not explain the absence of a ticket. This would explain it. Everything fits together."
"But suppose it were so, we are still as far as ever from unravelling the mystery of his death. Indeed, it becomes not simpler but stranger."
"Perhaps," said Holmes, thoughtfully, "perhaps." He relapsed into a silent reverie, which lasted until the slow train drew up at last in Woolwich Station. There he called a cab and drew Mycroft's paper from his pocket.
"We have quite a little round of afternoon calls to make," said he. "I think that Sir James Walter claims our first attention."
The house of the famous official was a fine villa with green lawns stretching down to the Thames. As we reached it the fog was lifting, and a thin, watery sunshine was breaking through. A butler answered our ring.
"Sir James, sir!" said he with solemn face. "Sir James died this morning."
"Good heavens!" cried Holmes in amazement. "How did he die?"
"Perhaps you would care to step in, sir, and see his brother, Colonel Valentine?"
"Yes, we had best do so."
We were ushered into a dim-lit drawing-room, where an instant later we were joined by a very tall, handsome, light-beared man of fifty, the younger brother of the dead scientist. His wild eyes, stained cheeks, and unkempt hair all spoke of the sudden blow which had fallen upon the household. He was hardly articulate as he spoke of it.
"It was this horrible scandal," said he. "My brother, Sir James, was a man of very sensitive honour, and he could not survive such an affair. It broke his heart. He was always so proud of the efficiency of his department, and this was a crushing blow."
"We had hoped that he might have given us some indications which would have helped us to clear the matter up."
"I assure you that it was all a mystery to him as it is to you and to all of us. He had already put all his knowledge at the disposal of the police. Naturally he had no doubt that Cadogan West was guilty. But all the rest was inconceivable."
"You cannot throw any new light upon the affair?"
"I know nothing myself save what I have read or heard. I have no desire to be discourteous, but you can understand, Mr. Holmes, that we are much disturbed at present, and I must ask you to hasten this interview to an end."
"This is indeed an unexpected development," said my friend when we had regained the cab. "I wonder if the death was natural, or whether the poor old fellow killed himself! If the latter, may it be taken as some sign of self-reproach for duty neglected? We must leave that question to the future. Now we shall turn to the Cadogan Wests."
A small but well-kept house in the outskirts of the town sheltered the bereaved mother. The old lady was too dazed with grief to be of any use to us, but at her side was a white-faced young lady, who introduced herself as Miss Violet Westbury, the fiancee of the dead man, and the last to see him upon that fatal night.
"I cannot explain it, Mr. Holmes," she said. "I have not shut an eye since the tragedy, thinking, thinking,
