Smiling Is Contagious
by Edward M. Grant
Tired of healing wounded soldiers on the borders of the British Empire, Doctor Cane returns to the heartlands of Victorian England. The quiet Oxfordshire village is a welcome break from war, until a smiling madman dies of a disease never seen before. After watching so many men die, Cane will do whatever it takes to keep the villagers alive. If they don't kill him first. 14,000 words of SF horror.
