When the narrator returns to his grandmother's house, he finds her dog pacing around the house. She tells him that she thinks the man who stole her granddaughter's purse is the culprit. The dog says that the man probably hid the wallet in the instrument shelter, the bird house, the sandbox, or the trashcan. He says that no one could have guessed that he was a grown man and that he would need to have a key to get into the trashcan or the sandbox. The narrator thanks the dog for his help and says that he cannot have done the crime without him.
