David reached for the sick man, lifting him as though he were a rag doll. Artificial respiration was useless. The Space Ranger had no illusion as to the possibility of recovery. He knew the symptoms—there had been many such cases lately—the sudden flushing, the loss of voice and breath, the hopeless minute’s fight for life, and then, the end. He turned to the trembling restaurant manager and identified himself. “My name is David Starr. I am a member of the Council of Science. What was the dead man eating before he collapsed?”
