who killed wellington in the curious incident of the dog in the nighttime
The Curious Incident of the Dog in the Night-Time Christopher's father, Ed, discovers the book and confiscates it after a brief fight with the boy. While searching for the confiscated book, Christopher uncovers a trove of letters which his mother wrote to him, dated after her supposed death, which his father has also hidden. He is so shocked by his father lying about his mother's death that he is unable to move, curls up on the bed, vomits and groans for several hours until his father returns home. Ed realizes that Christopher has read the letters and cleans him up. He then confesses that he had indeed lied about Judy's death and also that it was he who killed Wellington, stating that it was a mistake resulting from his anger after a heated argument with Mrs Shears. Christopher, having lost all trust in his father and fearing that Ed might try to kill him since he had already killed the dog, decides to live with his mother and runs away. He remembers his mother's address from the letters and embarks on an adventurous trip to London, where his mother lives with Mr Shears.
