"Surely it is far fetched?"

"Not a bit of it. Now listen to me carefully. I'll give you, step by step, the whole matter." He walked up and down for some minutes and then suddenly stopped beside me and thumped me on the back. "There's not a flaw in it!" he cried. "It's magnificent. My dear fellow, death is only a failure in human perfection. There's nothing mysterious in it. Religion has made a ridiculous fuss about it. There's nothing more mysterious in it than there is in a badly-oiled engine wearing out. Now listen. I'm going to begin...."

I listened, fascinated.

CHAPTER III

THE BUTTERFLIES

Two years passed by after my return to London without special incident, save that my black cat died. My work as a consulting physician occupied most of my time. In the greater world beyond my consulting-room door life went on undisturbed by any thought of the approaching upheaval, full of the old tragedies of ambition and love and sickness. But sometimes as I examined my patients and listened to their tales of suffering and pain, a curious contraction of the heart would come upon me at the thought that perhaps some day, not so very far remote, all the endless cycle of disease and misery would cease, and a new dawn of hope burst with blinding radiance upon weary humanity. And then a mood of unbelief would darken my mind and I would view the creation of the bacillus as an idle and vain dream, an illusion never to be realized....

One evening as I sat alone before my study fire, my servant entered and announced there was a visitor to see me.

"Show him in here," I said, thinking he was probably a late patient who had come on urgent business.

A moment later Professor Sarakoff himself was shown in.
