"I am he. Pray step in." The visitor looked somewhat astonished at having the door opened to him by the master of the house. "I wanted to have a few words." The doctor, a pale, nervous young man, dressed in an ultra-professional, long black frock-coat, with a high, white collar cutting off his dapper side-whiskers in the centre, rubbed his hands together and smiled. In the thick, burly man in front of him he scented a patient, and it would be his first. His scanty resources had begun to run somewhat low, and, although he had his first quarter's rent safely locked away in the right-hand drawer of his desk, it was becoming a question with him how he should meet the current expenses of his very simple housekeeping. He bowed, therefore, waved his visitor in, closed the hall door in a careless fashion, as though his own presence thereat had been a purely accidental circumstance, and finally led the burly stranger into his scantily furnished front room, where he motioned him to a seat. Dr. Wilkinson planted himself behind his desk, and, placing his finger-tips together, he gazed with some apprehension at his companion. What was the matter with the man? He seemed very red in the face. Some of his old professors would have diagnosed his case by now, and would have electrified the patient by describing his own symptoms before he had said a word about them. Dr. Horace Wilkinson racked his brains for some clue, but Nature had fashioned him as a plodder--a very reliable plodder and nothing more. He could think of nothing save that the visitor's watch-chain had a very brassy appearance, with a corollary to the effect that he would be lucky if he got half-a-crown out of him. Still, even half-a-crown was something in those early days of struggle. Whilst the doctor had been running his eyes over the stranger, the latter had been plunging his hands into pocket after pocket of his heavy coat. The heat of the weather, his dress, and this exercise of pocket-rummaging had all combined to still further redden his face, which had changed from brick to beet, with a gloss of moisture on his brow. This extreme ruddiness brought a clue at last to the observant doctor. Surely it was not to be attained without alcohol. In alcohol lay the secret of this man's trouble. Some little delicacy was needed, however, in showing him that he had read his case aright--that at a glance he had penetrated to the inmost sources of his ailments. "It's very hot," observed the stranger, mopping his forehead. "Yes, it is weather which tempts one to drink rather more beer than is good for one," answered Dr. Horace Wilkinson, looking very knowingly at his companion from over his finger-tips. "Dear, dear, you shouldn't do that." "I! I never touch beer." "Neither do I. I've been an abstainer for twenty years."
