THE FILTERABLE VIRUS
I was surprised to run into O'Hanlon himself in the train out to
Norwood. The failure to get Dr. Loeb troubled him and he had reasoned
that if Darius Moreton took the trouble to write a letter about his
friend he might possibly know more of his whereabouts than he professed.
We discussed the case nearly the whole journey, agreeing to separate
just before we reached the station in order not to be seen together.
It took me longer to carry out Kennedy's request than I had expected. I
found Myra at home alone, very much excited.
"Someone called me up from New York this morning," she said, "and asked
whether father and Lionel were at home. I thought they were at the
factory, but when I called there, the foreman told me they hadn't been
there. And Dr. Goode is out, too--hasn't seen any of his patients today.
Oh, Mr. Jameson, what does it all mean? Where have they gone?"
I was a poor one to comfort her, for I had no idea myself. Still, I did
my best, and incidentally secured the brushes, though I must confess I
had to commit a little second-story work to get into Dr. Goode's.
It seemed heartless to leave the poor girl all alone, but I knew that
Kennedy was waiting anxiously for me. I promised to make inquiries all
over about her father, Lionel, and Dr. Goode, and, I think, the mere
fact that someone showed an interest in her cheered her up, especially
when I told her Kennedy was working hard on the case.
As I waited for the train that was to take me back to the city, the
train from New York pulled in. Imagine my surprise when I saw Miss
Golder step off nervously and hurry up the main street.
I watched her, debating what to do, whether to let Kennedy wait and
follow her, or not.
"Someone, they don't know who, bailed her out," I heard a voice whisper
in my ear.
I turned quickly. It was O'Hanlon. "She put up cash bail," he added
under his breath. "No one knows where she got it. I'm waiting until she
turns that corner--then I'm going to shadow her. I can't seem to find
anyone in this town just now. Perhaps she knows where Loeb is."
"If you get on the trail, will you wire me?" I asked. "Here's my train
now."
O'Hanlon promised, and as I swung on the step I caught a last glimpse of
him sauntering casually in the direction Miss Golder had taken.
I handed Kennedy the brushes I had obtained, but he gave me no
opportunity to satisfy my curiosity. Instead, he started me out again to
keep in touch with the progress made in the cases of the quacks,
particularly the search for Dr. Loeb, which seemed to interest him quite
as much as the bailing out of Miss Golder.
It was after dinner and I was preparing to follow the cases on into the
night court, if necessary, when one of O'Hanlon's assistants hurried up
to me.
"We've just had a wire from Mr. O'Hanlon," he cried excitedly, handing
me a telegram.
I read:
"Loeb captured Norwood. Darius Moreton hiding him in vacant
house outside town. Advise Kennedy."
I dashed for the nearest telephone and called up Craig.
"Fine, Walter," he shouted back. "I am ready. Meet me at the station and
wire O'Hanlon to wait there for us."
We made the journey to Norwood as impatiently as any two passengers on
the accommodation at that hour of night, Craig carrying his evidence in
the case in a little leather hand satchel.
Already, out at the old house, O'Hanlon had gathered the Moreton family,
Dr. Goode, who had turned up with the rest, Dr. Loeb, and Miss Golder.
Myra Moreton was even more agitated than she had been when I left her
during the afternoon. In fact the secrecy maintained by both her family
and Dr. Goode, to say nothing of the presence of Dr. Loeb in the house
under arrest, had all but broken her down. She greeted Kennedy almost as
though he had been a life-long friend.
"I want you to look after Miss Moreton, Walter," he said in a low tone
as we three stood in the hall. "And you, Miss Moreton, I want to trust
me when I tell you I am going to bring you safely out of this thing. Be
a brave girl," he encouraged, taking her hand. "Remember that Mr.
Jameson and I are here solely in your interest."
"I know it," she murmured, her lip trembling. "I will try."
A moment later we entered the Moreton library. Dr. Loeb was glaring
impartially at everybody. I am sure that if he had been able to get at
any of his formidable electrical apparatus he would have made short work
of us "without cautery or knife." Darius Moreton was indignant, Lionel
supercilious, Dr. Goode silent.
Kennedy lost no time in getting down to the business that had brought
him out to Norwood, for this was not exactly a sociable gathering.
"Of course," he began, laying his leather case on the table and
unlocking, but not opening it, "references to cancer houses abound in
medical literature, but I think I am safe in saying that nothing has
been conclusively proved in favor either of the believers or the
skeptics. At least, it may be said to be an open question, with the
weight of opinion against it. Such physicians as Sir Thomas Oliver have
said that the evidence in favor is too strong to be ignored. Others,
equally brilliant, have shown why it should be ignored.
"In the absence of better proof--or rather in the presence of other
facts--perhaps, in this case, it would be better to see whether there is
not some other theory that may fit the facts better."
"Dr. Goode thought that the cancers might have been caused artificially
by X-rays or radium," I ventured.
Craig shook his head. "I have taken a piece of filter paper saturated
with a solution of potassium iodide, starch paste, and ferrosulphate and
laid it over a sample of blood, not four millimeters away. The whole I
have kept in the dark.
"Now, we know that blood gives off peroxide of hydrogen. Peroxide of
hydrogen is capable of attacking photographic plates. The paper can be
permeated by a gas. No, that was not a case of photo-activity observed
by Dr. Goode. It was the emission of gas from the blood that affected
the plates."
"But suppose that is the case," objected Dr. Goode hastily. "There are
the deaths from cancer. How do you explain them? It is not a cancer
house, you say. Is it mere chance?"
"Anyone may be pardoned for believing that cancer houses or even cancer
districts exist," reiterated Craig. "Indeed some observations seem to
show it, as I have said, though the opponents of the theory claim to
have found other causes. Here, as you hint, five people, living in close
association, have died in five years."
He paused and drew from the satchel the little porcelain cone which he
had picked up between the Moreton and Goode houses.
"I have here," he resumed, "what is known as a Berkefeld filter. Its
meshes let through none of the germs that we can see with a microscope.
It is bacteria-proof. Only something smaller than these things can pass
through it, something that we cannot see, a clear watery fluid. That
something in this case is a filterable virus."
Kennedy paused again, then went on, "Although the filterable viruses
have only recently come to attention, it is known that they are of very
diverse character. Here we have opened up the world of the infinitely
little--the universe that lies beyond the range of the microscope. The
study of these tiny particles is now one of the greatest objects in
scientific medicine.
"Are they living? It seems so, for a very little of the virus gives rise
to growths from which many others start. It may, of course, be chemical,
but it looks as if it were organic, since it resists cold, although not
heat, and can be destroyed by phenol, toluol, and other antiseptics.
Perhaps the virus may be visible, but not by any means yet known. Still,
we do know that these things which no eye can see may cause some of the
commonest diseases."
Kennedy paused. As usual he had his little audience following him
breathlessly. Even Dr. Loeb forgot to glower.
"In recent experiments with cancer in chickens," continued Craig, "tumor
material ground fine and treated in various ways has been filtered
through these filters. Cancers have been caused by this agent which has
passed through the filter.
"On the inside of the filter which I picked up back of this very house,
near the boundary of Dr. Goode's, I have found the giant cells of
cancer. On the outside was something which I have been able to develop
into a virus, these micro-organisms that belong to the ultra-invisible.
I do not pretend to know just how this bacteriological dwarf has been
used. But I know enough to say that someone has, without doubt, been
using some sort of filterable virus to induce cancers, just as the
experimenters at the Rockefeller Institute have done with animals.
"Naturally, in the Moreton family, this person found a fertile soil.
Perhaps he waited until he saw what looked like a favorable wound, or
traumatism. It is well-known that cancer often can be traced to a wound.
Perhaps he introduced this virus surreptitiously into a cut, now and
then. For, experiments show that the virus is strikingly dependent for
its action on the derangement of the tissues with which it is brought in
contact.
"This person must have had a high percentage of failures in his attempts
to inoculate the virus successfully. But by persistence and taking
advantage of every predisposition afforded by nature, he succeeded. At
any rate, this person must have been intimately acquainted with the
family, must have had some motive for seeking their deaths,--for
instance the family fortune.
"It makes no difference whether the victims might have had cancer sooner
or later, anyway. Even if that were so, this cold-blooded villain was at
least hastening the development, if not actually causing the frightful
and fatal disease."
Myra Moreton shuddered, and looked at Dr. Goode anxiously as Kennedy
proceeded. He seemed about to interrupt, but managed to check himself.
Craig reached over and picked out from the satchel the hat which we had
found on a desk at the office of the cancer quack.
"In the raid of Dr. Loeb's," he explained, changing tone, "a man
disappeared. I have here a soft hat which he left behind in his hurry to
escape, as well as some of the filters he was carrying."
He turned the hat inside out. "You will see," Craig pointed out, "that
on the felt of the inside there are numerous hairs, from the head of
the wearer."
I leaned forward, breathlessly. I began to see the part I had played in
building up his case.
"Human hair," he remarked, "differs greatly. Under the microscope one
may study the oval-shaped medulla, the long pointed cortex, and the flat
cuticle cells of an individual hair. The pigment in the cortex can be
studied also.
"I have taken some of the hairs from the inside of this hat, examined,
photographed, and measured them. I have compared them with a color scale
perfected by the late Alphonse Bertillon. In fact, in France quite a
science has been built up about hair by the so-called 'pilologists.' The
German scientific criminalists have written minute treaties on the hair
and astounding results have been obtained by them in detection.
"I have been able to secure samples of the hair of everyone in this case
and I have studied them also. These hairs in the hat which was left over
the package of filters have furnished me with a slender but no less
damning clew to a veritable monster."
One could have heard a pin drop, as if Kennedy were a judge pronouncing
a death sentence.
"Dr. Loeb is guilty of being one of the most heartless of quacks, it is
true," Kennedy's voice rang out tensely, as he faced us. "But the slow
murders, one by one, bringing the family estate nearer and nearer--they
were done by one who hoped to throw the blame on Dr. Loeb, by the man
whose hair I have here--Lionel Moreton."
