"Pardon, my dear Monsieur Bonacieux, if I don't stand upon ceremony," said d'Artagnan, "but nothing makes one so thirsty as want of sleep. I am parched with thirst. Allow me to take a glass of water in your apartment; you know that is never refused among neighbors."

Without waiting for the permission of his host, d'Artagnan went quickly into the house, and cast a rapid glance at the bed. It had not been used. Bonacieux had not been abed. He had only been back an hour or two; he had accompanied his wife to the place of her confinement, or else at least to the first relay.

"Thanks, Monsieur Bonacieux," said d'Artagnan, emptying his glass, "that is all I wanted of you. I will now go up into my apartment. I will make Planchet brush my boots; and when he has done, I will, if you like, send him to you to brush your shoes."

He left the mercer quite astonished at his singular farewell, and asking himself if he had not been a little inconsiderate.

At the top of the stairs he found Planchet in in a great fright.

"Ah, monsieur!" cried Planchet, as soon as he perceived his master, "here is more trouble. I thought you would never come in."

"What's the matter now, Planchet?" demanded d'Artagnan.

"Oh! I give you a hundred, I give you a thousand times to guess, monsieur, the visit I received in your absence."

"When?"

"About half an hour ago, while you were at Monsieur de Treville's."

"Who has been here? Come, speak."

"Monsieur de Cavois."

"Monsieur de Cavois?"

"In person."

"The captain of the cardinal's Guards?"

"Himself."

"Did he come to arrest me?"

"I have no doubt that he did, monsieur, for all his wheedling manner."

"Was he so sweet, then?"

"Indeed, he was all honey, monsieur."

"Indeed!"

"He came, he said, on the part of his Eminence, who wished you well, and to beg you to follow him to the Palais-Royal."*

*It was called the Palais-Cardinal before Richelieu gave it to the King.

"What did you answer him?"

"That the thing was impossible, seeing that you were not at home, as he could see."

"Well, what did he say then?"

"That you must not fail to call upon him in the course of the day; and then he added in a low voice, 'Tell your master that his Eminence is very well disposed toward him, and that his fortune perhaps depends upon this interview.'"

"The snare is rather MALADROIT for the cardinal," replied the young man, smiling.

"Oh, I saw the snare, and I answered you would be quite in despair on your return.

"'Where has he gone?' asked Monsieur de Cavois.

"'To Troyes, in Champagne,' I answered.

"'And when did he set out?'

"'Yesterday evening.'"

"Planchet, my friend," interrupted d'Artagnan, "you are really a precious fellow."

"You will understand, monsieur, I thought there would be still time, if you wish, to see Monsieur de Cavois to contradict me by saying you were not yet gone. The falsehood would then lie at my door, and as I am not a gentleman, I may be allowed to lie."

"Be of good heart, Planchet, you shall preserve your reputation as a veracious man. In a quarter of an hour we set off."

“Is there anything between the hedges and the walk?”

“Yes, there is a strip of grass about six feet broad on either side.”

“I understand that the yew hedge is penetrated at one point by a gate?”

“Yes, the wicket-gate which leads on to the moor.”

“Is there any other opening?”

“None.”

“So that to reach the Yew Alley one either has to come down it from the house or else to enter it by the moor-gate?”

“There is an exit through a summer-house at the far end.”

“Had Sir Charles reached this?”

“No; he lay about fifty yards from it.”

“Now, tell me, Dr. Mortimer—and this is important—the marks which you saw were on the path and not on the grass?”

“No marks could show on the grass.”

“Were they on the same side of the path as the moor-gate?”

“Yes; they were on the edge of the path on the same side as the moor-gate.”

“You interest me exceedingly. Another point. Was the wicket-gate closed?”

“Closed and padlocked.”

“How high was it?”

“About four feet high.”

“Then anyone could have got over it?”

“Yes.”

“And what marks did you see by the wicket-gate?”

“None in particular.”

“Good heaven! Did no one examine?”

“Yes, I examined myself.”

“And found nothing?”

“It was all very confused. Sir Charles had evidently stood there for five or ten minutes.”

“How do you know that?”

“Because the ash had twice dropped from his cigar.”

“Excellent! This is a colleague, Watson, after our own heart. But the marks?”

“He had left his own marks all over that small patch of gravel. I could discern no others.”

Sherlock Holmes struck his hand against his knee with an impatient gesture.

“If I had only been there!” he cried. “It is evidently a case of extraordinary interest, and one which presented immense opportunities to the scientific expert. That gravel page upon which I might have read so much has been long ere this smudged by the rain and defaced by the clogs of curious peasants. Oh, Dr. Mortimer, Dr. Mortimer, to think that you should not have called me in! You have indeed much to answer for.”

“I could not call you in, Mr. Holmes, without disclosing these facts to the world, and I have already given my reasons for not wishing to do so. Besides, besides —”

“Why do you hesitate?”

“There is a realm in which the most acute and most experienced of detectives is helpless.”

“You mean that the thing is supernatural?”

“I did not positively say so.”

“No, but you evidently think it.”

“Since the tragedy, Mr. Holmes, there have come to my ears several incidents which are hard to reconcile with the settled order of Nature.”
