When Helen left home to do some shopping, her elder daughter, 12-year -old Vanessa, was watching a movie and her little daughter, 10 month-old Alice, was asleep in the room. Helen told Vanessa to look after Alice and watch the cake in the oven (烤箱).
Just after Helen left, Alice woke up and got out of her bed. Vanessa didn't hear her sister because the film was making a noise. She also forgot the cake. But she heard the ice cream man. She ran out of the house without taking her key and locked herself out.
Through the window, she saw Alice in the room. At once, she remembered the cake and knew Alice was in danger. She ran to the nearest telephone box and called 999.
When the fireman arrived, they found Vanessa crying outside and heard Alice laughing inside. They went in and found the dog, Nap, playing with Alice. He was jumping around her and the oven.
When Nap saw the fireman, he stopped at once as if to say, “Now it's your turn. She is safe. ”The house was full of smoke then, and they believed that Nap was playing with Alice to keep her away from the oven.
