“I am afraid, Watson that I shall have to go,” said Holmes as we sat down together to our breakfast one morning.

“Go! Where to?”

“To Dartmoor; to King’s Pyland.”

I was not surprised. Indeed, my only wonder was that he had not already been mixed up in this extraordinary case, which was the one topic of conversation through the length and breadth of England. For a whole day my companion had rambled about the room with his chin upon his chest and his brows knitted, charging and recharging his pipe with the strongest black tobacco, and absolutely deaf to any of my questions or remarks. Fresh editions of every paper had been sent up by our news agent, only to be glanced over and tossed down into a corner. Yet, silent as he was, I knew perfectly well what it was over which he was brooding. There was but one problem before the public which could challenge his powers of analysis, and that was the singular disappearance of the favourite for the Wessex Cup, and the tragic murder of its trainer. When, therefore, he suddenly announced his intention of setting out for the scene of the drama, it was only what I had both expected and hoped for.

“I should be most happy to go down with you if I should not be in the way,” said I.

“My dear Watson, you would confer a great favour upon me by coming. And I think that your your time will not be misspent, for there are points about the case which promise to make it an absolutely unique one. We have, I think, just time to catch our train at Paddington, and I will go further into the matter upon our journey. You would oblige me by bringing with you your very excellent field-glass.”

And so it happened that an hour or so later I found myself in the corner of a first-class carriage flying along en route for Exeter, while Sherlock Holmes, with his sharp, eager face framed in his ear-flapped travelling-cap, dipped rapidly into the bundle of fresh papers which he had procured at Paddington. We had left Reading far behind us before he thrust the last one of them under the seat and offered me his cigar-case.

“We are going well,” said he, looking out of the window and glancing at his watch. “Our rate at present is fifty-three and a half miles an hour.”

“I have not observed the quarter-mile posts,” said I.

“Nor have I. But the telegraph posts upon this line are sixty yards apart, and the calculation is a simple one. I presume that you have looked into this matter of the murder of John Straker and the disappearance of Silver Blaze?”

“I have seen what the Telegraph and the Chronicle have to say.”

“It is one of those cases where the art of the reasoner should be used rather for the sifting of details than for the acquiring of fresh evidence. The tragedy has been so uncommon, so complete, and of such personal importance to so many people that we are suffering from a plethora of surmise, conjecture, and hypothesis. The difficulty is to detach the framework of fact — of absolute undeniable fact — from the embellishments of theorists and reporters. Then, having established ourselves upon this sound basis, it is our duty to see what inferences may be drawn and what are the special points upon which the whole mystery turns. On Tuesday evening I received telegrams from both Colonel Ross, the owner of the horse, and from Inspector Gregory, who is looking after the case, inviting my cooperation.”

"You acknowledge, then, the existence of the crime?"

"Yes, I see too plainly that it does exist. But it seems that it is intended to affect me personally. I fear an attack myself, after all these disasters."

"Oh, man," murmured d'Avrigny, "the most selfish of all animals, the most personal of all creatures, who believes the earth turns, the sun shines, and death strikes for him alone, -- an ant cursing God from the top of a blade of grass! And have those who have lost their lives lost nothing? -- M. de Saint-Meran, Madame de Saint-Meran, M. Noirtier" --

"How? M. Noirtier?"

"Yes; think you it was the poor servant's life was coveted? No, no; like Shakespeare's `Polonius,' he died for another. It was Noirtier the lemonade was intended for -- it is Noirtier, logically speaking, who drank it. The other drank it only by accident, and, although Barrois is dead, it was Noirtier whose death was wished for."

"But why did it not kill my father?"

"I told you one evening in the garden after Madame de Saint-Meran's death -- because his system is accustomed to that very poison, and the dose was trifling to him, which would be fatal to another; because no one knows, not even the assassin, that, for the last twelve months, I have given M. Noirtier brucine for his paralytic affection, while the assassin is not ignorant, for he has proved that brucine is a violent poison."

"Oh, have pity -- have pity!" murmured Villefort, wringing his hands.

"Follow the culprit's steps; he first kills M. de Saint-Meran" --

"O doctor!"

"I would swear to it; what I heard of his symptoms agrees too well with what I have seen in the other cases." Villefort ceased to contend; he only groaned. "He first kills M. de Saint-Meran," repeated the doctor, "then Madame de Saint-Meran, -- a double fortune to inherit." Villefort wiped the perspiration from his forehead. "Listen attentively."

"Alas," stammered Villefort, "I do not lose a single word."

"M. Noirtier," resumed M. d'Avrigny in the same pitiless tone, -- "M. Noirtier had once made a will against you -- against your family -- in favor of the poor, in fact; M. Noirtier is spared, because nothing is expected from him. But he has no sooner destroyed his first will and made a second, than, for fear he should make a third, he is struck down. The will was made the day before yesterday, I believe; you see there has been no time lost."

"Oh, mercy, M. d'Avrigny!"

"No mercy, sir! The physician has a sacred mission on earth; and to fulfil it he begins at the source of life, and goes down to the mysterious darkness of the tomb. When crime has been committed, and God, doubtless in anger, turns away his face, it is for the physician to bring the culprit to justice."

"Have mercy on my child, sir," murmured Villefort.

"You see it is yourself who have first named her -- you, her father."

"Have pity on Valentine! Listen -- it is impossible! I would as willingly accuse myself! Valentine, whose heart is pure as a diamond or a lily."

"No pity, procureur; the crime is fragrant. Mademoiselle herself packed all the medicines which were sent to M. de Saint-Meran; and M. de Saint-Meran is dead. Mademoiselle de Villefort prepared all the cooling draughts which Madame de Saint-Meran took, and Madame de Saint-Meran is dead. Mademoiselle de Villefort took from the hands of Barrois, who was sent out, the lemonade which M. Noirtier had every morning, and he has escaped by a miracle. Mademoiselle de Villefort is the culprit -- she is the poisoner! To you, as the king's attorney, I denounce Mademoiselle de Villefort, do your duty."
