The Curious Incident of the Dog in the Night-time

My prediction is that Mrs. Alexander was the murderer of the Wellington, because of how she acts around Christopher and the information she tells him. Hoodwinked is a movie telling an alternative story of Little Red Riding Hood and the animal that took all the recipes in the forest was the unsuspected bunny. Mrs. Alexander reminds me of the bunny because, like the bunny, she gives him information to forget about the case. She was the one to tell Christopher that his mom had an affair with Mr. Shears  and got him to think about his mother and not the murder. Also she wanted him to have tea and cookies during the case.
