The next day he returned to his work at the office, and his fellow-clerks, during the whole of the next week, noticed that he was more zealous and more painstaking than ever. On the other hand, his periodical fits of abstraction grew more frequent and more pronounced. On one occasion he took a paper to the head of the department for signature, and after it had been signed, instead of removing it from the table, he remained staring in front of him, and it was not until the head of the department had called him three times loudly by name that he took any notice and regained possession of his faculties. As these fits of absent-mindedness grew to be somewhat severely commented on, he consulted a doctor, who told him that what he needed was change of air, and advised him to spend his Sundays at Brighton or at some other bracing and exhilarating spot. Fletcher did not take the doctor’s advice, but continued spending his spare time as he did before, that is to say, in going to some big junction and watching the express trains go by all day long. One day while he was thus employed--it was Sunday, in August of 19--, when the Egyptian Exhibition was attracting great crowds of visitors--and sitting, as was his habit, on a bench on the centre platform of Slough Station, he noticed an Indian pacing up and down the platform, who every now and then stopped and regarded him with peculiar interest, hesitating as though he wished to speak to him. Presently the Indian came and sat down on the same bench, and after having sat there in silence for some minutes he at last made a remark about the heat. “Yes,” said Fletcher, “it is trying, especially for people like myself, who have to remain in London during these months.” “You are in an office, no doubt,” said the Indian. “Yes,” said Fletcher. “And you are no doubt hard worked.” “Our hours are not long,” Fletcher replied, “and I should not complain of overwork if I did not happen to suffer from--well, I don’t know what it is, but I suppose they would call it nerves.” “Yes,” said the Indian, “I could see that by your eyes.” “I am a prey to sudden fits of abstraction,” said Fletcher, “they are growing upon me. Sometimes in the office I forget where I am altogether for a space of about two or three minutes; people are beginning to notice it and to talk about it. I have been to a doctor, and he said I needed change of air. I shall have my leave in about a month’s time, and then perhaps I shall get some change of air, but I doubt if it will do me any good. But these fits are annoying, and once something quite uncanny seemed to happen to me.” The Indian showed great interest and asked for further details concerning this strange experience, and Fletcher told him all that he could recall--for the memory of it was already dimmed--of what had happened when he had telephoned that night.
