In the following January I took a partner in my practice. This was a step which I had long contemplated. I was a bachelor, making far too much money for my simple needs and working far too hard in order to accomplish it. I also wanted time for my investigations into the cause and treatment of a certain disease; these investigations have nothing to do with the story of Mala and her husband and would not interest laymen. I have no excuse but vanity for adding that they subsequently brought me some reputation. My partner was a sound and able young man, much interested in his profession, and soon made himself liked and respected. My life became much easier and more comfortable.
In the March following, about four one morning, I was awakened by the barking of a dog in the street outside my house. Presently I heard him scratching at my door. I hurried down, switched on the lights, and opened the door. I had thought of damage to my paint and not of Tarn, of whom I had heard nothing for a long time. But it was Tarn's dog that lay on the pavement outside.
I supposed at first that somebody at Felonsdene was ill, and that the dog had been sent to fetch me. But the dog's appearance did not bear this out. He had evidently come much further than the distance from Felonsdene to my house. He got up when he saw me, but the poor brute was so exhausted that he could hardly stand, and he looked as if he had been starved for days. I called him into the house and got food for him; he ate ravenously. I waited to see if he would try to get out again, but he seemed perfectly content to remain where he was. Finally, he followed me upstairs to my own room, where he stretched himself on the hearth-rug and almost instantly fell asleep. I was just about to switch off the light and get back into my bed again when I noticed the shining brass plate on the dog's collar. I bent down and examined it. On the brass plate, neatly engraved, were my own name and address. It looked as if the dog were to be mine in future. But why? What had happened?
The dog established definitely his relations with the rest of my household next morning. He took no notice whatever of anybody who left him alone. But he would allow nobody but myself to touch him. Even my partner, who understood dogs and was fond of them, had to confess himself beaten. He was taking the round that morning, and I intended to walk up to Felonsdene with the dog. But the poor brute was still so stiff and footsore that I decided after all to take the car. He sat beside me, and I rather think that he knew where he was going. But he showed no excitement when the car stopped, and made no attempt to rush off to the farm-house. He followed me quietly down the hill.
