“I think he’s in bed and asleep,” he said.

It was seven in the evening of a lovely summer’s day, but Dr. Watson was sufficiently familiar with the irregularity of his old friend’s hours to feel no surprise at the idea.

“That means a case, I suppose?”

“Yes, sir, he is very hard at it just now. I’m frightened for his health. He gets paler and thinner, and he eats nothing. ‘When will you be pleased to dine, Mr. Holmes?’ Mrs. Hudson asked. ‘Seven-thirty, the day after to-morrow,’ said he. You know his way when he is keen on a case.”

“Yes, Billy, I know.”

“He’s following someone. Yesterday he was out as a workman looking for a job. To-day he was an old woman. Fairly took me in, he did, and I ought to know his ways by now.” Billy pointed with a grin to a very baggy parasol which leaned against the sofa. “That’s part of the old woman’s outfit,” he said.

“But what is it all about, Billy?”

Billy sank his voice, as one who discusses great secrets of State. “I don’t mind telling you, sir, but it should go no farther. It’s this case of the Crown diamond.”

“What — the hundred-thousand-pound burglary?”

“Yes, sir. They must get it back, sir. Why, we had the Prime Minister and the Home Secretary both sitting sitting on that very sofa. Mr. Holmes was very nice to them. He soon put them at their ease and promised he would do all he could. Then there is Lord Cantlemere —”

“Ah!”

“Yes, sir, you know what that means. He’s a stiff’un, sir, if I may say so. I can get along with the Prime Minister, and I’ve nothing against the Home Secretary, who seemed a civil, obliging sort of man, but I can’t stand his Lordship. Neither can Mr. Holmes, sir. You see, he don’t believe in Mr. Holmes and he was against employing him. He’d rather he failed.”

“And Mr. Holmes knows it?”

“Mr. Holmes always knows whatever there is to know.”

“Well, we’ll hope he won‘t fail and that Lord Cantlemere will be confounded. But I say, Billy, what is that curtain for across the window?”

“Mr. Holmes had it put up there three days ago. We’ve got something funny behind it.”

Billy advanced and drew away the drapery which screened the alcove of the bow window.

Dr. Watson could not restrain a cry of amazement. There was a facsimile of his old friend, dressing-gown and all, the face turned three-quarters towards the window and downward, as though reading an invisible book, while the body was sunk deep in an armchair. Billy detached the head and held it in the air.

“We put it at different angles, so that it may seem more lifelike. I wouldn’t dare touch it if the blind were not down. But when it’s up you can see this from across the way.”

“We used something of the sort once before.”

Lupin exclaimed:

"What! Did Daubrecq plot the present business?"

"No, no, that is only an accident. The hateful prophecy was just a wish which he expressed. But oh, how it terrified me! I was ailing at the time; my other son, my little Jacques, had just been born. And every day we heard of some fresh misdeed of Gilbert's - forgeries, swindles - so much so that we spread the news, in our immediate surroundings, of his departure for abroad, followed by his death. Life was a misery; and it became still more so when the political storm burst in which my husband was to meet his death."

"What do you mean?"

"A word will be enough: my husband's name was on the list of the Twenty-seven."

"Ah!"

The veil was suddenly lifted from Lupin's eyes and he saw, as in a flash of lightning, a whole legion of things which, until then, had been hidden in the darkness.

Clarisse Mergy continued, in a firmer voice:

"Yes, his name was on it, but by mistake, by a piece of incredible ill-luck of which he was the victim. It is true that Victorien Mergy was a member of the committee appointed to consider the question of the Two-Seas Canal. It is true that he voted with the members who were in favour of the company's scheme. He was even paid - yes, I tell you so plainly and I will mention the sum - he was paid fifteen thousand francs. But he was paid on behalf of another, of one of his political friends, a man in whom he had absolute confidence and of whom he was the blind, unconscious tool. He thought he was showing his friend a kindness; and it proved his own undoing. It was not until the day after the suicide of the chairman of the company and the disappearance of the secretary, the day on which the affair of the canal was published in the papers, with its whole series of swindles and abominations, that my husband knew that a number of his fellow-members had been bribed and learnt that the mysterious list, of which people suddenly began to speak, mentioned his name with theirs and with the names of other deputies, leaders of parties and influential politicians. Oh, what awful days those were! Would the list be published? Would his name come out? The torture of it! You remember the mad excitement in the Chamber, the atmosphere of terror and denunciation that prevailed. Who owned the list? Nobody could say. It was known to be in existence and that was all. Two names were sacrificed to public odium. Two men were swept away by the storm. And it remained unknown where the denunciation came from and in whose hands the incriminating documents were."

"Daubrecq," suggested Lupin.

"No, no!" cried Madame Mergy. "Daubrecq was nothing at that time: he had not yet appeared upon the scene. No, don't you remember, the truth came out suddenly through the very man who was keeping it back: Germineaux, the ex-minister of justice, a cousin of the chairman of the Canal Company. As he lay dying of consumption, he wrote from his sick-bed to the prefect of police, bequeathing him that list of names, which, he said, would be found, after his death, in an iron chest in the corner of his room. The house was surrounded by police and the prefect took up his quarters by the sick man's bedside. Germineaux died. The chest was opened and found to be empty."
