The Improbable Adventures of Sherlock Holmes Part 60

I will not sign myself Vernet, and until the hunt is done and the world restored, I beg you to think of me simply as, Rache Rache Inspector Lestrade ran from the room, calling to his men. They made young Wiggins take them to the place where the man had given him the note, for all the world as if Vernet the actor would be waiting there for them, a-smoking of his pipe. From the window we watched them run, my friend and I, and we shook our heads.

"They will stop and search all the trains leaving London, all the s.h.i.+ps leaving Albion for Europe or the New World," said my friend, "looking for a tall man and his companion, a smaller, thickset medical man, with a slight limp. They will close the ports. Every way out of the country will be blocked."

"Do you think they will catch him, then?"

My friend shook his head. "I may be wrong," he said, "but I would wager that he and his friend are even now only a mile or so away, in the Rookery of St. Giles, where the police will not go except by the dozen. They will hide up there until the hue and cry have died away. And then they will be about their business."

"What makes you say that?"

"Because," said my friend, "if our positions were reversed, it is what I would do. You should burn the note, by the way."

I frowned. "But surely it's evidence," I said.

"It's seditionary nonsense," said my friend.

And I should have burned it. Indeed, I told Lestrade I had had burned it, when he returned, and he congratulated me on my good sense. Lestrade kept his job, and Prince Albert wrote a note to my friend congratulating him on his deductions while regretting that the perpetrator was still at large. burned it, when he returned, and he congratulated me on my good sense. Lestrade kept his job, and Prince Albert wrote a note to my friend congratulating him on his deductions while regretting that the perpetrator was still at large.

They have not yet caught Sherry Vernet, or whatever his name really is, nor was any trace found of his murderous accomplice, tentatively identified as a former military surgeon named John (or perhaps James) Watson. Curiously, it was revealed that he had also been in Afghanistan. I wonder if we ever met.

My shoulder, touched by the Queen, continues to improve; the flesh fills and it heals. Soon I shall be a dead shot once more.

One night when we were alone, several months ago, I asked my friend if he remembered the correspondence referred to in the letter from the man who signed himself Rache. Rache. My friend said that he remembered it well, and that "Sigerson" (for so the actor had called himself then, claiming to be an Icelander) had been inspired by an equation of my friend's to suggest some wild theories furthering the relations.h.i.+p between ma.s.s, energy, and the hypothetical speed of light. "Nonsense, of course," said my friend, without smiling. "But inspired and dangerous nonsense nonetheless."

"Nonsense, of course," said my friend, without smiling. "But inspired and dangerous nonsense nonetheless."

The palace eventually sent word that the Queen was pleased with my friend's accomplishments in the case, and there the matter has rested.

I doubt my friend will leave it alone, though; it will not be over until one of them has killed the other.

I kept the note. I have said things in this retelling of events that are not to be said. If I were a sensible man I would burn all these pages, but then, as my friend taught me, even ashes can give up their secrets. Instead, I shall place these papers in a strongbox at my bank with instructions that the box may not be opened until long after anyone now living is dead. Although, in the light of the recent events in Russia, I fear that day may be closer than any of us would care to think.

"Where is everybody?" These words, exclaimed by Los Alamos physicist Enrico Fermi in 1950, led to his formulation of what's known as the Fermi paradox: Why haven't we found any evidence of extraterrestrial life, given the seemingly high probability that such life exists? Even if intelligent life evolves only rarely, the sheer scale of the universe would mean that advanced civilizations should be commonplace. (The Drake equation is a well-known model for organizing this line of reasoning.) There ought to be civilizations billions of years older than ours, in which case they should have colonized Earth long ago, or at least built large engineering projects such as Dyson spheres that we could detect with our instruments. But so far, nothing. Many explanations have been proposed, including that intelligence is much rarer than we think, that advanced civilizations tend to destroy themselves or each other, or that advanced civilizations have chosen not to talk to us, perhaps because they don't want to meddle with our development or because we're just too primitive to bother with. Our final tale presents a solution to the Fermi paradox that we can virtually guarantee you've never considered before.

I had been pulled into the future first, ahead of my companion. There was no sensation a.s.sociated with the chronotransference, except for a popping of my ears which I was later told had to do with a change in air pressure. Once in the twenty-first century, my brain was scanned in order to produce from my memories a perfect reconstruction of our rooms at 221B Baker Street. Details that I could not consciously remember or articulate were nonetheless reproduced exactly: the flock-papered walls, the bearskin hearthrug, the basket chair and the armchair, the coal-scuttle, even the view through the window-all were correct to the smallest detail.

I was met in the future by a man who called himself Mycroft Holmes. He claimed, however, to be no relation to my companion, and protested that his name was mere coincidence, although he allowed that the fact of it was likely what had made a study of my partner's methods his chief avocation. I asked him if he had a brother called Sherlock, but his reply made little sense to me: "My parents weren't that that cruel." cruel."

In any event, this Mycroft Holmes-who was a small man with reddish hair, quite unlike the stout and dark ale of a fellow with the same name I had known two hundred years before-wanted all details to be correct before he whisked Holmes here from the past. Genius, he said, was but a step from madness, and although I had taken to the future well, my companion might be quite rocked by the experience.

When Mycroft did bring Holmes forth, he did so with great stealth, transferring him precisely as he stepped through the front exterior door of the real 221 Baker Street and into the simulation that had been created here. I heard my good friend's voice down the stairs, giving his usual glad tidings to a simulation of Mrs. Hudson. His long legs, as they always did, brought him up to our humble quarters at a rapid pace.

I had expected a hearty greeting, consisting perhaps of an ebullient cry of "My Dear Watson," and possibly even a firm clasping of hands or some other display of bonhomie. But there was none of that, of course. This was not like the time Holmes had returned after an absence of three years during which I had believed him to be dead. No, my companion, whose exploits it has been my honor to chronicle over the years, was unaware of just how long we had been separated, and so my reward for my vigil was nothing more than a distracted nodding of his drawn-out face. He took a seat and settled in with the evening paper, but after a few moments, he slapped the newsprint sheets down. "Confound it, Watson! I have already read this edition. Have we not today's today's paper?" paper?"

And, at that turn, there was nothing for it but for me to adopt the unfamiliar role that queer fate had dictated I must now take: our traditional positions were now reversed, and I would have to explain the truth to Holmes.

"Holmes, my good fellow, I am afraid they do not publish newspapers anymore."

He pinched his long face into a scowl, and his clear, gray eyes glimmered. "I would have thought that any man who had spent as much time in Afghanistan as you had, Watson, would be immune to the ravages of the sun. I grant that today was unbearably hot, but surely your brain should not have addled so easily."

"Not a bit of it, Holmes, I a.s.sure you," said I. "What I say is true, although I confess my reaction was the same as yours when I was first told. There have not been any newspapers for seventy-five years now."

"Seventy-five years? Watson, this copy of The Times The Times is dated August the fourteenth, 1899-yesterday." is dated August the fourteenth, 1899-yesterday."

"I am afraid that is not true, Holmes. Today is June the fifth, anno Domini anno Domini two thousand and ninety-six." two thousand and ninety-six."

"Two thou-"

"It sounds preposterous, I know-"

"It is is preposterous, Watson. I call you 'old man' now and again out of affection, but you are in fact nowhere near two hundred and fifty years of age." preposterous, Watson. I call you 'old man' now and again out of affection, but you are in fact nowhere near two hundred and fifty years of age."

"Perhaps I am not the best man to explain all this," I said.

"No," said a voice from the doorway. "Allow me."

Holmes surged to his feet. "And who are you?"

"My name is Mycroft Holmes."

"Impostor!" declared my companion.

"I a.s.sure you that that is not the case," said Mycroft. "I grant I'm not your brother, nor a habitue of the Diogenes Club, but I do share his name. I am a scientist-and I have used certain scientific principles to pluck you from your past and bring you into my present."

For the first time in all the years I had known him, I saw befuddlement on my companion's face. "It is quite true," I said to him.

"But why?" said Holmes, spreading his long arms. "a.s.suming this mad fantasy is true-and I do not grant for an instant that it is-why would you thus kidnap myself and my good friend, Dr. Watson?"

"Because, Holmes, the game, as you used to be so fond of saying, is afoot."

"Murder, is it?" asked I, grateful at last to get to the reason for which we had been brought forward.

"More than simple murder," said Mycroft. "Much more. Indeed, the biggest puzzle to have ever faced the human race. Not just one body is missing. Trillions are. Trillions. Trillions."

"Watson," said Holmes, "surely you recognize the signs of madness in the man? Have you nothing in your bag that can help him? The whole population of the Earth is less than two thousand millions."

"In your time, yes," said Mycroft. "Today, it's about eight thousand million. But I say again, there are trillions more who are missing."

"Ah, I perceive at last," said Holmes, a twinkle in his eye as he came to believe that reason was once again holding sway. "I have read in The Ill.u.s.trated London News The Ill.u.s.trated London News of these of these dinosauria dinosauria, as Professor Owen called them-great creatures from the past, all now deceased. It is their demise you wish me to unravel."

Mycroft shook his head. "You should have read Professor Moriarty's monograph called The Dynamics of an Asteroid The Dynamics of an Asteroid," he said.

"I keep my mind clear of useless knowledge," replied Holmes curtly.

Mycroft shrugged. "Well, in that paper Moriarty quite cleverly guessed the cause of the demise of the dinosaurs: an asteroid cras.h.i.+ng into earth kicked up enough dust to block the sun for months on end. Close to a century after he had reasoned out this hypothesis, solid evidence for its truth was found in a layer of clay. No, that mystery is long since solved. This one is much greater."

"And what, pray, is it?" said Holmes, irritation in his voice.

Mycroft motioned for Holmes to have a seat, and, after a moment's defiance, my friend did just that. "It is called the Fermi paradox," said Mycroft, "after Enrico Fermi, an Italian physicist who lived in the twentieth century. You see, we know now that this universe of ours should have given rise to countless planets, and that many of those planets should have produced intelligent civilizations. We can demonstrate the likelihood of this mathematically, using something called the Drake equation. For a century and a half now, we have been using radio-wireless, that is-to look for signs of these other intelligences. And we have found nothing-nothing! Hence the paradox Fermi posed: if the universe is supposed to be full of life, then where are the aliens?" Hence the paradox Fermi posed: if the universe is supposed to be full of life, then where are the aliens?"

"Aliens?" said I. "Surely they are mostly still in their respective foreign countries."

Mycroft smiled. "The word has gathered additional uses since your day, good doctor. By aliens, I mean extraterrestrials-creatures who live on other worlds."

"Like in the stories of Verne and Wells?" asked I, quite sure that my expression was agog.

"And even in worlds beyond the family of our sun," said Mycroft.

Holmes rose to his feet. "I know nothing of universes and other worlds," he said angrily. "Such knowledge could be of no practical use in my profession."

I nodded. "When I first met Holmes, he had no idea that the Earth revolved around the sun." I treated myself to a slight chuckle. "He thought the reverse to be true."

Mycroft smiled. "I know of your current limitations, Sherlock." My friend cringed slightly at the overly familiar address. "But these are mere gaps in knowledge; we can rectify that easily enough."

"I will not crowd my brain with useless irrelevancies," said Holmes. "I carry only information that can be of help in my work. For instance, I can identify one hundred and forty different varieties of tobacco ash-"

"Ah, well, you can let that information go, Holmes," said Mycroft. "No one smokes anymore. It's been proven ruinous to one's health." I shot a look at Holmes, whom I had always warned of being a self-poisoner. "Besides, we've also learned much about the structure of the brain in the intervening years. Your fear that memorizing information related to fields such as literature, astronomy, and philosophy would force out other, more relevant data, is unfounded. The capacity for the human brain to store and retrieve information is almost infinite."

"It is?" said Holmes, clearly shocked.

"It is."

"And so you wish me to immerse myself in physics and astronomy and such all?"

"Yes," said Mycroft.

"To solve this paradox of Fermi?"

"Precisely!"

"But why me?"

"Because it is a puzzle puzzle, and you, my good fellow, are the greatest solver of puzzles this world has ever seen. It is now two hundred years after your time, and no one with a facility to rival yours has yet appeared."

Mycroft probably could not see it, but the tiny hint of pride on my longtime companion's face was plain to me. But then Holmes frowned. "It would take years to ama.s.s the knowledge I would need to address this problem."

"No, it will not." Mycroft waved his hand, and amidst the homely untidiness of Holmes's desk appeared a small sheet of gla.s.s standing vertically. Next to it lay a strange metal bowl. "We have made great strides in the technology of learning since your day. We can directly program new information into your brain." Mycroft walked over to the desk. "This gla.s.s panel is what we call a monitor monitor. It is activated by the sound of your voice. Simply ask it questions, and it will display information on any topic you wish. If you find a topic that you think will be useful in your studies, simply place this helmet on your head" (he indicated the metal bowl), "say the words 'load topic,' and the information will be seamlessly integrated into the neural nets of your very own brain. It will at once seem as if you know, and have always known, all the details of that field of endeavor."

"Incredible!" said Holmes. "And from there?"

"From there, my dear Holmes, I hope that your powers of deduction will lead you to resolve the paradox-and reveal at last what has happened to the aliens!"

"Watson! Watson!"

I awoke with a start. Holmes had found this new ability to effortlessly absorb information irresistible and he had pressed on long into the night, but I had evidently fallen asleep in a chair. I perceived that Holmes had at last found a subst.i.tute for the sleeping fiend of his cocaine mania: with all of creation at his fingertips, he would never again feel that emptiness that so destroyed him between a.s.signments.

"Eh?" I said. My throat was dry. I had evidently been sleeping with my mouth open. "What is it?"

"Watson, this physics is more fascinating than I had ever imagined. Listen to this, and see if you do not find it as compelling as any of the cases we have faced to date."

I rose from my chair and poured myself a little sherry-it was, after all, still night and not yet morning. "I am listening."

"Remember the locked and sealed room that figured so significantly in that terrible case of the Giant Rat of Sumatra?"

"How could I forget?" said I, a s.h.i.+ver traversing my spine. "If not for your keen shooting, my left leg would have ended up as gamy as my right."

"Quite," said Holmes. "Well, consider a different type of locked-room mystery, this one devised by an Austrian physicist named Erwin Schrodinger. Imagine a cat sealed in a box. The box is of such opaque material, and its walls are so well insulated, and the seal is so profound, that there is no way anyone can observe the cat once the box is closed."

"Hardly seems cricket," I said, "locking a poor cat in a box."

"Watson, your delicate sensibilities are laudable, but please, man, attend to my point. Imagine further that inside this box is a triggering device that has exactly a fifty-fifty chance of being set off, and that this aforementioned trigger is rigged up to a cylinder of poison gas. If the trigger is tripped, the gas is released, and the cat dies."

"Goodness!" said I. "How nefarious."

"Now, Watson, tell me this: without opening the box, can you say whether the cat is alive or dead?"

"Well, if I understand you correctly, it depends on whether the trigger was tripped."

"Precisely!"

"And so the cat is perhaps alive, and, yet again, perhaps it is dead."

"Ah, my friend, I knew you would not fail me: the blindingly obvious interpretation. But it is wrong, dear Watson, totally wrong."

"How do you mean?"

"I mean the cat is neither alive nor is it dead. It is a potential potential cat, an unresolved cat, a cat whose existence is nothing but a question of possibilities. It is neither alive nor dead, Watson-neither! Until some intelligent person opens the box and looks, the cat is unresolved. Only the act of looking forces a resolution of the possibilities. Once you crack the seal and peer within, the potential cat collapses into an actual cat. Its reality is cat, an unresolved cat, a cat whose existence is nothing but a question of possibilities. It is neither alive nor dead, Watson-neither! Until some intelligent person opens the box and looks, the cat is unresolved. Only the act of looking forces a resolution of the possibilities. Once you crack the seal and peer within, the potential cat collapses into an actual cat. Its reality is a result of a result of having been observed." having been observed."
