"Let the doctor pass," the commissioner said, "but alone. Make every one go out, and shut the porte-cochere."

On reaching the landing the commissioner stopped to look at the brown stain which, running under the door, spread over the tiling, as Caffie never had had a mat.

"It is certainly a stain of blood," Saniel said, who stopped to examine it and dipped his finger in it.

"Open the door," the commissioner said to the locksmith.

The latter examined the lock, looked among his keys, selected one, and unlocked the door.

"Let no one enter," the commissioner said. "Doctor, have the goodness to follow me."

And, going ahead, he entered the first office, that of the clerk, followed by Saniel. Two little rills of blood, already thickened, starting from Caffie's chair, and running across the tiled floor, which sloped a little toward the side of the staircase, joined in the stain which caused the discovery of the crime. The commissioner and Saniel took care not to step in it.

"The unfortunate man has had his throat cut," Saniel said. "Death must have occurred two or three hours ago. There is nothing to do."

"Speak for yourself, doctor."

And, stooping, he picked up the knife.

"Is it not a butcher's knife?" asked Saniel, who could only use this word.

"It looks like it."

He had raised Caffie's head and examined the wound.

"You see," he said, "that the victim has been butchered. The stroke was from left to right, by a firm hand which must be accustomed to handle this knife. But it is not only a strong and practised hand that has done this deed; it was guided by an intelligence that knew how to proceed to insure a quick, almost instantaneous death, and at the same time a silent one."

"You think it was done by a butcher?"

"By a professional killer; the larynx has been cut above the glottis, and with the same stroke the two carotid arteries, with the jugular veins. As the assassin had to raise the head, the victim was not able to cry out; considerable blood has flowed, and death must have ensued in one or two minutes."

"The scene appears to me very well reconstructed."

"The blood should have burst out in this direction," Saniel continued, pointing to the door. "But as this door was open, nothing is to be seen."

While Saniel spoke, the commissioner threw a glance about the room—the glance of the police, which takes in everything.

"The safe is open," he said. "The affair becomes clear; the assassination was followed by theft."

There was a door opposite to the entrance, which the commissioner opened; it was that of Caffie's bedroom.

"I will give you a man to help you carry the body into this room, where you can continue your examination more easily, while I will continue my investigations in this office."

Saniel would have liked to remain in the office to assist at these investigations, but it was impossible to raise an objection. The chair was rolled into the bedroom, where two candles had been lighted on the mantel, and when the body was laid on the bed, the commissioner returned to the office.

Saniel made his examination last as long a time as possible, to the end that he need not leave the house; but he could not prolong it beyond certain limits. When they were reached, he returned to the clerk's office, where the commissioner had installed himself, and was hearing the concierge's deposition.

"And so," he said, "from five to seven o'clock no one asked for M.
Caffie?"

"No one. But I left my lodge at a quarter past five to light the gas on the stairs; that took me twenty minutes, because I am stiff in my joints, and during this time some one might have gone up and down the stairs without my seeing them."

"Well," the commissioner said, turning to Saniel, "have you found any distinguishing feature?"

"No; there is only the wound on the neck."

"Will you draw up your medico-legal report while I continue my inquest?"

"Willingly."

And, without waiting, he seated himself at the clerk's desk, facing the commissioner's secretary, who had arrived a few minutes previous.

"I am going to make you take the oath," the commissioner said.

After this formality Saniel began his report:

"We, the undersigned, Victor Saniel, doctor of medicine of the Paris Faculty, residing in Paris in the Rue Louis-le-Grand, after having taken an oath to fulfil in all honor and conscience the mission confided to us—"

All the time that he was writing he paid attention to everything that was said, and did not lose one word of the concierge's deposition.

"I am certain," she said, "that from half-past five until now no one has gone up or down the stairs but the people who live in the house."

"But before half-past five?"

"I have told you that from a quarter past five until half-past I was not in my lodge."

"And before a quarter past five o'clock?"

"Several persons passed whom I did not know."

"Did any one among them ask you for Monsieur Caffie?"

"No; that is to say, yes. There was one who asked me if Monsieur Caffie was at home; but I know him well; that is why I answered No."

"And who is he?"

"One of Monsieur Caffies old clerks."

"His name?"

"Monsieur Florentin—Monsieur Florentin Cormier."

Saniel's hand was arrested at this name, but he did not raise his head.

"At what hour did he come?" asked the commissioner.

"Near three o'clock, before rather than after."

"Did you see him go away?"

"Certainly, he spoke to me."

"What time was it?"

"Half-past three."

"Do you think that death could have occurred at this moment?" the commissioner asked, turning to Saniel.

"No; I think it must have been between five and six o'clock."

"It is wrong for the commissioner to suspect Monsieur Florentin," cried the concierge. "He is a good young man, incapable of harming a fly. And then, there is a good reason why death could not have taken place between three o'clock and half-past; it is that Monsieur Caffie's lamp was lighted, and you know the poor gentleman was not a man to light his lamp in broad daylight, looking as he was—"

She stopped abruptly, striking her forehead with her hand.

"That is what I remember, and you will see that Monsieur Florentin has nothing to do with this affair. As I went upstairs at a quarter past five to light my gas, some one came behind me and rang Monsieur Caffie's bell, and rapped three or four times at equal distances, which is the signal to open the door."

Again Saniel's pen stopped, and he was obliged to lean his hand on the table to prevent its trembling.

"Who was it?"

"Ah! That I do not know," she answered. "I did not see him, but I heard him, the step of a man. It was this rascal who killed him, you may be sure."

This seemed likely.

"He went out while I was on the stairs; he knew the customs of the house."

Saniel continued his report.

After having questioned and
