Kellie looked for Sebastian's mum at home, but she was not there. Kellie thought about it and went to the cafe. She saw a lot of people there. One of them was a police officer. Mrs Clifford and Mum were sitting and talking with the police officer.
"Kellie!" - Mum came over to the dog.
"Where is Sebastian?" Kellie gave Mum the note and she read it aloud. "The robber is at 10, Sainsbury Street. Get the police!"
"What a brave boy, and what a smart dog you are!" said the polise officer. "Go straight to the police car. Hurry up!"
Sebastian was standing behind a tree waiting for Kellie. He knew Kellie and Mum would be back soon. But he couldn't see the robber anymore. Suddenly the door opened and the robber came out house.
