"How do you know?" I said fiercely. "There's no proof. It's all theory so far. The calculations may be wrong."

The man stared at me wonderingly. He saw me as a man fighting with some strange anxiety, with his forehead damp and shining, his spectacles aslant on his nose and the heavy folds of his frock-coat shaken with a sudden impetuosity.

"How do you know?" I repeated, shaking my fist in the air. "How do you know he isn't going to die?"

Sarakoff fingered his beard in silence, but his eyes shone with a quiet certainty. To the man from Birmingham it must have seemed suddenly strange that we should behave in this manner. His mind was sharpened to perceive things. Yesterday, had he been present at a similar scene, he would probably have sat dully, finding nothing curious in my pa.s.sionate att.i.tude and the calm, almost insolent, inscrutability of Sarakoff. He forgot his turquoise finger nails, and stared, open-mouthed.

"Ain't going to die?" he said. "What do yer mean?"

"Simply that you aren't going to die," was Sarakoff's soft answer.

"Yer mean, not die of the Blue Disease?"

"Not die at all."

"Garn! Not die at all." He looked at me. "What's he mean, Mister?" He looked almost surprised with himself at catching the drift of Sarakoff's sentence. Inwardly he felt something insistent and imperious, forcing him to grasp words, to blunder into new meanings. Some new force was alive in him and he was carried on by it in spite of himself. He felt strung up to a pitch of nervous irritation. He got up from his chair and came forward, pointing at Sarakoff. "What's this?" he demanded. "Why don't you speak out? Yer cawn't hide it from me." He stopped. His brain, working at unwonted speed, had discovered a fresh suspicion. "Look 'ere, you two know something about this blue disease." He came a step closer, and looking cunningly in my face, said: "That's why you offered me a five-pound note, ain't it?"

I avoided the scrutiny of the sparrow-egg blue orbs close before me.

"I offered you the money because I wished to examine you," I said shortly. "Here it is. You can go now."

I took a note from a safe in the corner of the room, and held it out.

The man took it, felt its crispness and stowed it away in a secure pocket. His thoughts were temporarily diverted by the prospect of an immediate future with plenty of money, and he picked up his hat and went to the door. But his turquoise finger nails lying against the rusty black of the hat brought him back to his suspicions. He paused and turned.

"My name's Wain," he said. "I'm telling you, in case you might 'ear of me again. 'Erbert Wain. I know what yours is, remember, because I seed it on the door." He twisted his hat round several times in his hands and drew his brows together, puzzled at the speed of his ideas. Then he remembered the card that Symington-Tearle had given him.

He pulled it out and examined it. "I'm going across to see this gent,"

he announced. "It's convenient, 'im living so close. Perhaps he'll 'ave a word to say about this 'ere disease. Fair spread over Birmingham, so they say. It would be nasty if any bloke was responsible for it. Good day to yer." He opened the door slowly, and glanced back at us standing in the middle of the room watching him. "Look 'ere," he said swiftly, "what did 'e mean, saying I was never going to die and----" The light from the window was against his eyes, and he could not see the features of Sarakoff's face, but there was something in the outline of his body that checked him. "Guv'ner, it ain't true." The words came hoa.r.s.ely from his lips. "I ain't never not going to die."

Sarakoff spoke.

"You are never going to die, Mr. Herbert Wain ... you understand?...

_Never_ going to die, unless you get killed in an accident--or starve."

I jerked up my hand to stop my friend.

Wain stared incredulously. Then he burst into a roar of laughter and smacked his thigh.

"Gor lumme!" he exclaimed, "if that ain't rich. Never going to die! Live for ever! Strike me, if that ain't a notion!" The tears ran down his cheeks and he paused to wipe them away. "If I was to believe what you say," he went on, "it would fair drive me crazy. Live for ever--s'elp me, if that wouldn't be just 'ell. Good-day to yer, gents. I'm obliged to yer."

He went out into the sunlit street still roaring with laughter, a thin, ragged, tattered figure, with the shadow of immortality upon him.

CHAPTER X

THE ILLNESS OF MR. ANNOT

The departure of Mr. Herbert Wain was a relief. I turned to Sarakoff at once and spoke with some heat.

"You were more than imprudent to give that fellow hints that we knew more about the Blue Disease than anybody else," I exclaimed. "This may be the beginning of incalculable trouble."

"Nonsense," replied the Russian. "You are far too apprehensive, Harden.

What can he do?"

"What may he not do?" I cried bitterly. "Do you suppose London will welcome the spread of the germ? Do you think that people will be pleased to know that you and I were responsible for its appearance?"

"When they realize that it brings immortality with it, they will hail us as the saviours of humanity."

"Mr. Herbert Wain did not seem to accept the idea of immortality with any pleasure," I muttered. "The suggestion seemed to strike him as terrible."

Sarakoff laughed genially.

"My friend," he said, "Mr. Herbert Wain is not a man of vision. He is a c.o.c.kney, brought up in the streets of a callous city. To him life is a hard struggle, and immortality naturally appears in a poor light. You must have patience. It will take some time before the significance of this immortality is grasped by the people. But when it is grasped, all the conditions of life will change. Life will become beautiful. We will have reforms that, under ordinary circ.u.mstances, would have taken countless ages to bring about. We will antic.i.p.ate our evolution by thousands of centuries. At one step we will reach the ultimate goal of our destiny."

"And what is that?"

"Immortality, of course. Surely you must see by now that all the activities of modern life are really directed towards one end--towards solving the riddle of prolonging life and at the same time increasing pleasure? Isn't that the inner secret desire that you doctors find in every patient? So far a compromise has only been possible, but now that is all changed."

"I don't agree, Sarakoff. Some people must live for other motives. Take myself ... I live for science."

"It is merely your form of pleasure."

"That's a quibble," I cried angrily. "Science is aspiration. There's all the difference in the world between aspiration and pleasure. I have scarcely known what pleasure is. I have worked like a slave all my life, with the sole ambition of leaving something permanent behind me when I die."

"But you won't die," interposed the Russian. "That is the charm of the new situation."

"Then why should I work?" The question shaped itself in my mind and I uttered it involuntarily. I sat down and stared at the fire. A kind of dull depression came over me, and for some reason the picture of Sarakoff's b.u.t.terflies appeared in my mind. I saw them with great distinctness, crawling aimlessly on the floor of their cage. "Why should I work?" I repeated.

Sarakoff merely shrugged his shoulders and turned away. Questions of that kind did not seem to bother him. His was a nature that escaped the necessity of self-a.n.a.lysis. But I was different, and our conversation had aroused a train of odd thought. What, after all, was it that kept my nose to the grindstone? Why had I slaved incessantly all my life, reading when I might have slept, examining patients when I might have been strolling through meadows, hurrying through meals when I might have eaten at leisure? What was the cause behind all the tremendous activity and feverish haste of modern people? When Sarakoff had said that I would not die, and that therein lay the charm of the new situation, it seemed as if scales had momentarily fallen from my eyes. I beheld myself as something ridiculous, comparable to a hare that persists in dashing along a country lane in front of the headlight of a motor car, when a turn one way or another would bring it to safety. A great uneasiness filled me, and with it came a determination to ignore these new fields of thought that loomed round me--a determination that I have seen in old men when they are faced by the new and contradictory--and I began to force my attention elsewhere. I was relieved when the door opened and my servant entered. She handed me a telegram. It was from Miss Annot, asking me to come to Cambridge at once, as her father was seriously ill.

I scribbled a reply, saying I would be down that afternoon.

After the servant had left the room, I remained gazing at the fire, but my depression left me. In place of it I felt a quiet elation, and it was not difficult for me to account for it.

"I was wrong in saying that I had scarcely known what pleasure is," I observed at length, looking up at Sarakoff with a smile. "I must confess to you that there is one factor in my life that gives me great pleasure."

Sarakoff placed himself before me, hands in pockets and pipe in mouth, and gazed at me with an answering smile in his dark face.

"A woman?"

I flushed. The Russian seemed amused.

"I thought as much," he remarked. "This year I noticed a change in you.

Your fits of abstraction suggested it. Well, may I congratulate you?

When are you to be married?"

"That is out of the question at present," I answered hurriedly. "In fact, there is no definite arrangement--just a mutual understanding....
