“I take it you were in bed?” questioned Dunbar, turning again to the doctor.

“I had been in bed about a quarter of an hour when I was aroused by the ringing of the door-bell.  This ringing struck me as so urgent that I ran out in my pajamas, and found there Mr. Leroux, in a very disturbed state—­”

“What did he say?  Give his own words as nearly as you remember them.”

Leroux, who had been standing, sank slowly back into the armchair, with his eyes upon Dr. Cumberly as the latter replied:—­

“He said ’Cumberly!  Cumberly!  For God’s sake, come down at once; there is a strange woman in my flat, apparently in a dying condition!’”

“What did you do?”

“I ran into my bedroom and slipped on my dressing-gown, leaving Mr. Leroux in the entrance-hall.  Then, with the clock chiming the last stroke of midnight, we came out together and I closed my door behind me.  There was no light on the stair; but our conversation—­Mr. Leroux was speaking in a very high-pitched voice"...

“What was he saying?”

“He was explaining to me how some woman, unknown to him, had interrupted his work a few minutes before by ringing his door-bell."...

Inspector Dunbar held up his hand.

“I won’t ask you to repeat what he said, doctor; Mr. Leroux, presently, can give me his own words.”

“We had descended to this floor, then,” resumed Cumberly, “when Mr. Exel, entering below, called up to us, asking if anything was the matter.  Leroux replied, ’Matter, Exel!  There’s a devil of a business!  For mercy’s sake, come up!’”

“Well?”

“Mr. Exel thereupon joined us at the door of this flat.”

“Was it open?”

“Yes.  Mr. Leroux had rushed up to me, leaving the door open behind him.  The light was out, both in the lobby and in the study, a fact upon which I commented at the time.  It was all the more curious as Mr. Leroux had left both lights on!"...

“Did he say so?”

“He did.  The circumstances surprised him to a marked degree.  We came in and I turned up the light in the lobby.  Then Leroux, entering the study, turned up the light there, too.  I entered next, followed by Mr. Exel—­and we saw the body lying where you see it now.”

“Who saw it first?”

“Mr. Leroux; he drew my attention to it, saying that he had left her lying on the chesterfield and not upon the floor.”

“You examined her?”

“I did.  She was dead, but still warm.  She exhibited signs of recent illness, and of being addicted to some drug habit; probably morphine.  This, beyond doubt, contributed to her death, but the direct cause was asphyxiation.  She had been strangled!”

“My God!” groaned Leroux, dropping his face into his hands.

“You found marks on her throat?”

“The marks were very slight.  No great pressure was required in her weak condition.”
