The Mysterious Nighttime Murder of the Dog

Fifteen-year-old Christopher Boone is autistic. He is a talented mathematician and a very smart boy, but his sharp memory and lively mind do not help him in life. Until one night, to be precise, at seven minutes past midnight, he is caught in the neighbor's backyard. Nearby lies a mutilated dog. Now Christopher is a suspect! Will the boy be able to conduct an investigation and prove to those around him that he has nothing to do with the death of the defenseless animal? Or does he?
