missed someone and skewered a stray dog. Carry this on a little further. Give one of these people power
and opportunity to loose death at random, death whose cause he is sure cannot be detected. He sits in
his obscurity, in safety, a god of death. With no special malice against anyone, perhaps-impersonal, just
shooting his arrows in the air, like Longfellow's archer, for the fun of it."
"And you wouldn't call such a person a homicidal maniac?" I asked, dryly.
"Not necessarily. Merely free of inhibitions against killing. He might have no consciousness of wrongdoing
whatever. Everybody comes into this world under sentence of death-time and method of execution
unknown. Well, this killer might consider himself as natural as death itself. No one who believes that
things on earth are run by an all-wise, all-powerful God thinks of Him as a homicidal maniac. Yet He
looses wars, pestilences, misery, disease, floods, earthquakes-on believers and unbelievers alike. If you
believe things are in the hands of what is vaguely termed Fate-would you call Fate a homicidal maniac?"
"Your hypothetical archer," I said, "looses a singularly unpleasant arrow, Braile. Also, the discussion is
growing far too metaphysical for a simple scientist like me. Ricori, I can't lay this matter before the police.
They would listen politely and laugh heartily after I had gone. If I told all that is in my mind to the medical
authorities, they would deplore the decadence of a hitherto honored intellect. And I would rather not call
in any private detective agency to pursue inquiries."
"What do you want me to do?" he asked.
"You have unusual resources," I answered. "I want you to sift every movement of Peters and Hortense
Darnley for the past two months. I want you to do all that is possible in the same way with the others-"
I hesitated.
"I want you to find that one place to which, because of their love for children, each of these unfortunates
was drawn. For though my reason tells me you and Braile have not the slightest real evidence upon which
to base your suspicions, I grudgingly admit to you that I have a feeling you may be right."
"You progress, Dr. Lowell," Ricori said, formally. "I predict that it will not be long before you will as
grudgingly admit the possibility of my witch."
"I am sufficiently abased," I replied, "by my present credulity not to deny even that."
Ricori laughed, and busied himself copying the essential information from the reports. Ten o'clock struck.
McCann came up to say that the car was waiting and we accompanied Ricori to the door. The gunman
had stepped out and was on the steps when a thought came to me.
"Where do you begin, Ricori?"
"With Peters' sister."
"Does she know Peters is dead?"
"No," he answered, reluctantly. "She thinks him away. He is often away for long, and for reasons which
she understands he is not able to communicate with her directly. At such times I keep her informed. And
the reason I have not told her of Peters' death is because she dearly loved him and would be in much
sorrow-and in a month, perhaps, there is to be another baby."
"Does she know the Darnley woman is dead, I wonder?"
"I do not know. Probably. Although McCann evidently does not."
"Well," I said, "I don't see how you're going to keep Peters' death from her now. But that's your
business."
"Exactly," he answered, and followed McCann to the car.
Braile and I had hardly gotten back to my library when the telephone rang. Braile answered it. I heard
him curse, and saw that the hand that held the transmitter was shaking. He said: "We will come at once."
He set the transmitter down slowly, then turned to me with twitching face.
"Nurse Walters has it!"
I felt a distinct shock. As I have written, Walters was a perfect nurse, and besides that a thoroughly good
and attractive young person. A pure Gaelic type-blue black hair, blue eyes with astonishingly long
lashes, milk-white skin-yes, singularly attractive. After a moment or two of silence I said:
"Well, Braile, there goes all your fine-spun reasoning. Also your murder theory. From the Darnley
woman to Peters to Walters. No doubt now that we're dealing with some infectious disease."
"Isn't there?" he asked, grimly. "I'm not prepared to admit it. I happen to know Walters spends most of
her money on a little invalid niece who lives with her-a child of eight. Ricori's thread of common interest
moves into her case."
"Nevertheless," I said as grimly, "I intend to see that every precaution is taken against an infectious
malady."
By the time we had put on our hats and coats, my car was waiting. The hospital was only two blocks
away, but I did not wish to waste a moment. I ordered Nurse Walters removed to an isolated ward used
for observation of suspicious diseases. Examining her, I found the same flaccidity as I had noted in the
case of Peters. But I observed that, unlike him, her eyes and face showed little of terror. Horror there
was, and a great loathing. Nothing of panic. She gave me the same impression of seeing both within and
