"Fight tuberculosis, folks". Christmas Eve, an old junkie selling. Christmas seals. On North Park Street. The "Priest" they called him. "Fight tuberculosis, folks"
People hurried by, gray shadows on a distant wall. It was getting late and no money to score. He turned into a side street and the lake wind hit him like a knife. Cab stop just ahead under a streetlight. 
Boy got out with a suitcase. Thin kid in prep school clothes. Familiar face, the Priest told himself. Watching from the doorway.
"Reminds me of something a long time ago". The boy, there, with his overcoat. Unbuttoned, reaching into his pants pocket for the cab fare. The cab drove away and turned the corner. The boy went inside a building.
"Hmm, yes, maybe," the suitcase was there in the doorway. The boy nowhere in sight. Gone to get the keys, most likely, have to move fast.
He picked up the suitcase and started for the corner. Made it, glanced down at the case. It didn't look like the case the boy had or any boy would have. The Priest couldn't put his finger on what was so old about the case. Old and dirty, poor quality leather and heavy. Better see what's inside.
He turned into Lincoln Park. Found an empty place and opened the case. Two severed human legs that belonged to a young man. With dark skin, shiny black leg hairs. . Glittered in the dim streetlight. The legs had been forced into the case. And he had to use his knee on the back of the case to shove them out. "Legs, yet," he said and walked quickly away with the case. Might bring a few dollars to score.
The buyer sniffed suspiciously. "Kind of a funny smell about it". "It's just Mexican leather". "Well, some joker didn't cure it".
The buyer looked at the case with cold disfavor. "Not even right sure he killed it, whatever it is. Three is the best I can do and it hurts. But since this is Christmas and you're the Priest". He slipped three bills under the table into the Priest's dirty hand. The Priest faded into the street shadows, seedy and furtive. Three cents didn't buy a bag, nothing less than a nickel. Say, remember that old Addie croaker told me not [bad word] back. Unless I paid him the three cents I owe him. Yeah, isn't that a [bad word] for ya, blow your stack about three lousy cents. The doctor was not pleased to see him. 
"Now, what do you want? I told you!" The Priest laid three bills on the table. The doctor put the money in his pocket and started to scream. "I've had trouble! People have been around! I may lose my license!" The Priest just sat there. Eyes, old and heavy with years of junk, on the doctor's face. "I can't write you a prescription". The doctor jerked open a drawer. And slid an ampule across the table. "That's all I have in the office!" The doctor stood up. "Take it and get out!" he screamed, hysterical.
The Priest's expression did not change. 
The doctor added in quieter tones. "After all, I'm a professional man. And I shouldn't be bothered by people like you". "Is that all you have for me? One lousy quarter G? Couldn't you lend me a nickel?" "Get out, get out, I'll call the police I tell you". "All right, doctor, I'm going". 
Of course it was cold and far walk to rooming house. shabby street, room on the top floor. "These stairs," coughed the Priest. There pulling himself up along the banister. He went into the bathroom. Yellow wall panels, toilet dripping. And got his works from under the washbasin. Wrapped in brown paper, back to his room. Get every drop in the dropper. 
He rolled up his sleeve. Then he heard a groan from next door. Room 18, the Mexican kid lived there. The Priest had passed him on the stairs. And saw the kid was hooked. But he never spoke because he didn't want any juvenile connections. Bad news in any language.
