"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."
