At any event, he claims to have come from the Englischer Hof. A woman has been taken ill but refuses for some reason to be seen by a Swiss physician. This is what he says. And what would you do if you were Watson? Would you refuse to believe this unlikely story and stay put or would you abandon your friend — at the worst possible time and in a truly infernal place? That’s all we ever hear about the Swiss boy, by the way — although you and I will meet him again soon enough. Watson suggests that he may have been working for Moriarty but does not mention him again. As for Watson, he takes his leave and hurries off to his non-existent patient; generous but wrong-headed to the last.
We must now wait three years for Holmes’s reappearance — and it is important to remember that, to all intents and purposes, as far as this narrative is concerned, it is believed that he is dead. Only much later does he explain himself (Watson relates it all in ‘The Adventure of the Empty House’), and although I have read many written statements in my line of work, few of them have managed to stack up quite so many improbabilities. This is his account, however, and we must, I suppose, take it at face value.
After Watson has left, according to Holmes, Professor James Moriarty makes his appearance, walking along the narrow path that curves halfway around the falls. This path comes to an abrupt end, so there can be no question of Holmes attempting to escape — not that such a course of action would ever have crossed his mind. Give him his due: this is a man who has always faced his fears square on, whether they be a deadly swamp adder, a hideous poison that might drive you to insanity or a hell-hound set loose on the moors. Holmes has done many things that are, frankly, baffling — but he has never run away.
The two men exchange words. Holmes asks permission to leave a note for his old companion and Professor Moriarty agrees. This much at least can be verified for those three sheets of paper are among the most prized possessions of the British Library Reading Room in London where I have seen them displayed. However, once these courtesies have been dispensed with, the two men rush at each other in what seems to be less a fight, more a suicide pact, each determined to drag the other into the roaring torrent of water. And so it might have been. But Holmes still has one trick up his sleeve. He has learned
Moriarty is taken by surprise. He is propelled over the edge and, with a terrible scream, plunges into the abyss. Holmes sees him brush against a rock before he disappears into the water. He himself is safe … Forgive me, but is there not something a little unsatisfactory about this encounter? You have to ask yourself why Moriarty allows himself to be challenged in this way. Old-school heroics are all very well (although I’ve never yet met a criminal who went in for them) but what possible purpose can it have served to endanger himself? To put it bluntly, why didn’t he simply take out a revolver and shoot his opponent at close range?
If that is strange, Holmes’s behaviour now becomes completely inexplicable. On the spur of the moment, he decides to use what has just occurred to feign his own death. He climbs up the rock face behind the path and hides there until Watson returns. In this way, of course, there will be no second set of footprints to show that he has survived. What’s the point? Professor Moriarty is now dead and the British police have announced that the entire gang has been arrested so why does he still believe himself to be in danger? What exactly is there to be gained? If I had been Holmes, I would have hurried back to the Englischer Hof for a nice Wiener schnitzel and a celebratory glass of Neuchâtel.
Meanwhile, Dr Watson, realising he has been tricked, rushes back to the scene, where an abandoned alpenstock and a set of footprints tell their own tale. He summons help and investigates the scene with several men from the hotel and a local police officer by the name of Gessner. Holmes sees them but does not make himself known, even though he must be aware of the distress it will cause his most trusted companion. They find the letter. They read it and, realising there is nothing more to be done, they all leave. Holmes begins to climb down again and it is now that the narrative takes another unexpected and wholly inexplicable turn. It appears that Professor Moriarty has not come to the Reichenbach Falls alone. As Holmes begins his descent — no easy task in itself — a man suddenly appears and attempts to knock him off his perch with a number of boulders. The man is Colonel Sebastian Moran.
