He looked helpless as he said to Ann: "I don't know quite what to do. The flesh starts to hemorrhage when I pull at the cloth. She'd bleed to death if I yanked it off. But it's such an extreme allergy that it may kill her, if we leave it in contact with the skin."
The manky's rattle suddenly began rhythmically from the lower part of the house. Ann clutched the side of the chair, trying to keep herself under control. A siren wailed somewhere down the street, grew louder rapidly, suddenly going silent at the peak of its crescendo.
Dr. Schwartz glanced outside the window. "An ambulance. Looks as if they're stopping here."
"Oh, no," Ann breathed. "Something's happened to Les."
"It sure will," Les said grimly, walking into the bedroom. "I won't have a job if I can't get this stuff off my fingers. Big black fingerprints on everything I touch. I can't handle correspondence or shake hands with customers. How's the kid? What's the ambulance doing out front?"
"They're going to the next house down the street," the physician said. "Has there been sickness there?"
Les held up his hands, palms toward the doctor. "What's wrong with me? My fingers look all right. But they leave black marks on everything I touch."
The doctor looked closely at the fingertips. "Every human has natural oil on the skin. That's how detectives get results with their fingerprint powder. But I've never heard of nigrification, in this sense. Better not try to commit any crimes until you've seen a skin specialist."
Ann was peering through the window, curious about the ambulance despite her own troubles. She saw two attendants carry Mr. Burnett, motionless and white, on a stretcher from the house next door into the ambulance. A third member of the crew was struggling with a disheveled Mrs. Burnett at the door. Shrieks that sounded like "Murder!" came sharply through the window.
