Seb and Mama go to visit Mrs Kenny, but there's a dog called Hamish at the house too. Woof woof, says Hamish. "Home," says Seb in a little voice. While Mama and Mrs Kenny have tea, Hamish is shut in another room and Seb plays with his train set . He gets so absorbed he forgets all about Hamish - until a piece of his cookie slips under the door. Seb puts his finger through the gap, peeps under the door, and two gentle eyes look back at him. "Hello, Hamish," says Seb. When it's time to go home, Mama looks everywhere for Seb. Where could he be? Seb and Hamish are found at last, curled up together, fast asleep!
