The summer was unreasonably hot and rainless, and Maxley suffered much from drought, and also from a plague of big black night-flying gnats, the bite of which was very irritating and virulent. They came sailing in of an evening, settling on one’s skin so quietly that one perceived nothing till the sharp stab announced that one had been bitten. They did not bite the hands or face, but chose always the neck and throat for their feeding-ground, and most of us, as the poison spread, assumed a temporary goitre. Then about the middle of August appeared the first of those mysterious cases of illness which our local doctor attributed to the long-continued heat coupled with the bite of these venomous insects. The patient was a boy of sixteen or seventeen, the son of Mrs. Amworth’s gardener, and the symptoms were an anæmic pallor and a languid prostration, accompanied by great drowsiness and an abnormal appetite. He had, too, on his throat two small punctures where, so Dr. Ross conjectured, one of these great gnats had bitten him. But the odd thing was that there was no swelling or inflammation round the place where he had been bitten. The heat at this time had begun to abate, but the cooler weather failed to restore him, and the boy, in spite of the quantity of good food which he so ravenously swallowed, wasted away to a skin-clad skeleton. I met Dr. Ross in the street one afternoon about this time, and in answer to my inquiries about his patient he said that he was afraid the boy was dying. The case, he confessed, completely puzzled him: some obscure form of pernicious anæmia was all he could suggest. But he wondered whether Mr. Urcombe would consent to see the boy, on the chance of his being able to throw some new light on the case, and since Urcombe was dining with me that night, I proposed to Dr. Ross to join us. He could not do this, but said he would look in later. When he came, Urcombe at once consented to put his skill at the other’s disposal, and together they went off at once. Being thus shorn of my sociable evening, I telephoned to Mrs. Amworth to know if I might inflict myself on her for an hour. Her answer was a welcoming affirmative, and between piquet and music the hour lengthened itself into two. She spoke of the boy who was lying so desperately and mysteriously ill, and told me that she had often been to see him, taking him nourishing and delicate food. But to-day--and her kind eyes moistened as she spoke--she was afraid she had paid her last visit. Knowing the antipathy between her and Urcombe, I did not tell her that he had been called into consultation; and when I returned home she accompanied me to my door, for the sake of a breath of night air, and in order to borrow a magazine which contained an article on gardening which she wished to read.
