A teenage boy stands on stage with a large stuffed dog. Sticking out of its side is a small pitchfork, similar to the ones gardeners use to turn their compost heaps. Christopher knows the canine is named Wellington and that he belongs to a neighbor. A policeman questions the boy about the dog’s death. “I did not kill the dog,” Christopher blankly tells the bobby. Thus begins “The Curious Incident of the Dog in the Night-time” to be performed this weekend at Hammond Hall in Winter Harbor.
