I stooped down and turned the body over. The policemen watched me in silence. The body was that of a young, fair-haired sailor man. There was a knife between his ribs. His eyes were screwed up into a rigid state of contraction which death had not yet relaxed. His whole body was rigid. I knew that the knife had pierced his heart. But the most extraordinary thing about him was his expression. I have never looked on a face either in life or death that expressed such terror. Even the policemen were startled. The light of their lamps shone on that monstrous and distorted countenance, and we gazed in horrified silence.

"Is he dead?" asked one at last.

"Quite dead," I replied, "but it is odd to find this rigidity so early." I began to press his eyelids apart. The right eye opened. I uttered a cry of astonishment.

"Look!" I cried.

They stared.

"Blest if that ain't queer," said one. "It's that Blue Disease. He must 'ave come from Birmingham."

"Queer?" I said passionately. "Why, man, it's tragedy—unadulterated tragedy. The man was an Immortal."

They stared at me heavily.

"Immortal?" said one.

"He would have lived for ever," I said. "In his system there is the most marvellous germ that the world has ever known. It was circulating in his blood. It had penetrated to every part of his body. A few minutes ago, as he walked along the dark street, he had before him a future of unnumbered years. And now he lies in the gutter. Can you imagine a greater tragedy?"
