As for the tumultuous twenty-four hours since his landing, the Professor preferred not to include them in his retrospect. It was enough that they were over. “All I want is quiet,” he had said to the doctors who, after his alarming attack of influenza, followed by bronchial pneumonia, had ordered an immediate departure for warmer climes; and they had thrust him onto an excursion-steamer jammed with noisy sight-seers, and shipped him to a port whither all the rest of the world appeared to be bound at the same moment! His own fault, perhaps? Well—he never could plan or decide in a hurry, and when, still shaken by illness, he had suddenly been told that he must spend six months in a mild climate, and been faced with the alternatives of southern California or southern France, he had chosen the latter because it meant a more complete escape from professional associations and the terror of meeting people one knew. As far as climate went, he understood the chances to be equal; and all he wanted was to recover from his pulmonary trouble and employ his enforced leisure in writing a refutation of Einstein’s newly published book on Relativity.

Once the Professor had decided on the south of France, there remained the difficulty of finding, in that populous region, a spot quiet enough to suit him; but after much anxious consultation with colleagues who shared his dread of noise and of promiscuous human intercourse, he had decided on a secluded pension high up in the hills, between Monte Carlo and Mentone. In this favoured spot, he was told, no dogs barked, cocks crew or cats courted. There were no waterfalls, or other sonorous natural phenomena, and it was utterly impossible for a motor (even with its muffler knocked off) to ascend the precipitous lane which led to the pension. If, in short, it were possible to refute Einstein’s theory, it was in just such a place, and there only, that the feat might be accomplished.

Once settled in the train, the Professor breathed more freely. Most of his fellow-passengers had stayed on the ship, which was carrying them on to swarm over a succession of other places as he had just left them swarming over Marseilles. The train he got into was not very crowded, and should other travellers enter the compartment, his ear-pads would secure him from interruption. At last he could revert to the absorbing thought of the book he was planning; could plunge into it like a diver into the ocean. He drew a deep breath and plunged....

Certainly the compartment had been empty when the train left Marseilles—he was sure of that; but he seemed to remember now that a man had got in at a later station, though he couldn’t have said where or when; for once he began to think, time vanished from him as utterly as space.

He became conscious of the intruding presence only from the smell of tobacco gradually insinuating itself into his nostrils. Very gradually; for when the Professor had withdrawn into his inner stronghold of Pure Reason, and pulled up the ladder, it was not easy for any appeal to reach him through the channel of the senses. Not that these were defective in him. Far from it: he could smell and see, taste and hear, with any man alive; but for many years past he had refrained from exercising these faculties except in so far as they conduced to the maintenance of life and security. He would have preferred that the world should contain nothing to see, nothing to smell, nothing to hear; and by negativing persistently every superfluous hint of his visual, auditive or olfactory organs he had sheathed himself in a general impenetrability of which the ear-pads were merely a restricted symbol.

His noticing the whiff of tobacco was an accident, a symptom of his still disorganized state; he put the smell resolutely from him, registered “A Man Opposite,” and plunged again into the Abstract.

Once—about an hour later, he fancied—the train stopped with a jerk which flung him abruptly out of his corner. His mental balance was disturbed, and for one irritating instant his gaze unwillingly rested on silver groves, purple promontories and a blue sea. “Ugh—scenery!” he muttered; and with a renewed effort of the will he dropped his mental curtain between that inconsequent jumble of phenomena and the absolutely featureless area in which the pure intellect thrones. The incident had brought back the smell of his neighbour’s cigarette; but the Professor sternly excluded that also, and the train moved on....

Professor Hibbart was in truth a man of passionately excitable nature: no one was ever, by temperament, less adapted to the lofty intellectual labours in which his mind delighted. He asked only to live in the empyrean; but he was perpetually being dragged back to earth by the pity, wrath or contempt excited in him by the slipshod course of human affairs. There were only two objects on which he flattered himself he could always look with a perfectly unseeing eye; and these were a romantic landscape and a pretty woman. And he was not absolutely sure about the landscape.

Suddenly a touch, soft yet peremptory, was laid on his arm. Looking down, he beheld a gloved hand; looking up he saw that the man opposite him was a woman.

To this awkward discovery he was still prepared to oppose the blank wall of the most complete imperception. But a sharp pinch proved that the lady who had taken hold of his arm had done so with the fixed determination to attract his attention, at the cost of whatever pain or inconvenience to himself. As she appeared also to be saying something—probably asking if the next station were the one at which she ought to get out—he formed with soundless lips the word “Deaf,” and pointed to his ears. The lady’s reply was to release his wrist, and with her free hand flick off an ear-pad.
