At this moment the door opened briskly behind them, and the doctor came out with his hat on. He put a long envelope into the priest’s hands.
“That’s the document you wanted,” he said, “and I must be getting home. Good night.”
“Good night,” said Father Brown, as the doctor walked briskly to the gate. He had left the front door open, so that a shaft of gaslight fell upon them. In the light of this Brown opened the envelope and read the following words:
DEAR FATHER BROWN,—Vicisti Galilee. Otherwise, damn your
eyes, which are very penetrating ones. Can it be possible that
there is something in all that stuff of yours after all?
I am a man who has ever since boyhood believed in Nature and
in all natural functions and instincts, whether men called them
moral or immoral. Long before I became a doctor, when I was a
schoolboy keeping mice and spiders, I believed that to be a good
animal is the best thing in the world. But just now I am shaken;
I have believed in Nature; but it seems as if Nature could betray
a man. Can there be anything in your bosh? I am really getting
morbid.
I loved Quinton’s wife. What was there wrong in that? Nature
told me to, and it’s love that makes the world go round. I also
thought quite sincerely that she would be happier with a clean
animal like me than with that tormenting little lunatic. What was
there wrong in that? I was only facing facts, like a man of
science. She would have been happier.
According to my own creed I was quite free to kill Quinton,
which was the best thing for everybody, even himself. But as a
healthy animal I had no notion of killing myself. I resolved,
therefore, that I would never do it until I saw a chance that
would leave me scot free. I saw that chance this morning.
I have been three times, all told, into Quinton’s study today.
The first time I went in he would talk about nothing but the weird
tale, called “The Cure of a Saint,” which he was writing, which
was all about how some Indian hermit made an English colonel kill
himself by thinking about him. He showed me the last sheets, and
even read me the last paragraph, which was something like this:
“The conqueror of the Punjab, a mere yellow skeleton, but still
gigantic, managed to lift himself on his elbow and gasp in his
nephew’s ear: ‘I die by my own hand, yet I die murdered!’” It so
happened by one chance out of a hundred, that those last words
were written at the top of a new sheet of paper. I left the room,
and went out into the garden intoxicated with a frightful
opportunity.
We walked round the house; and two more things happened in my
favour. You suspected an Indian, and you found a dagger which the
Indian might most probably use. Taking the opportunity to stuff
it in my pocket I went back to Quinton’s study, locked the door,
and gave him his sleeping draught. He was against answering
Atkinson at all, but I urged him to call out and quiet the fellow,
because I wanted a clear proof that Quinton was alive when I left
the room for the second time. Quinton lay down in the conservatory,
and I came through the study. I am a quick man with my hands, and
in a minute and a half I had done what I wanted to do. I had
emptied all the first part of Quinton’s romance into the fireplace,
where it burnt to ashes. Then I saw that the quotation marks
wouldn’t do, so I snipped them off, and to make it seem likelier,
snipped the whole quire to match. Then I came out with the
knowledge that Quinton’s confession of suicide lay on the front
table, while Quinton lay alive but asleep in the conservatory
beyond.
The last act was a desperate one; you can guess it: I pretended
to have seen Quinton dead and rushed to his room. I delayed you
with the paper, and, being a quick man with my hands, killed
Quinton while you were looking at his confession of suicide. He
was half-asleep, being drugged, and I put his own hand on the
knife and drove it into his body. The knife was of so queer a
shape that no one but an operator could have calculated the angle
that would reach his heart. I wonder if you noticed this.
