The Mystery of the Missing Cake

John is a detective. He lives in a small town. He likes his job, but sometimes it is very quiet. One day, his phone rings. It's Mrs. Smith. She says, 'My cake is missing. I am sad. Can you help me?'

John goes to Mrs. Smith's house. He looks for clues. He sees a big, wet paw print on the kitchen floor. 'Aha!' thinks John. He is going to solve the mystery soon.

John finds Mr. Smith's big dog in the garden. It looks happy, but its mouth is messy with cake crumbs. John laughs. 'The mystery is solved. The dog ate the cake!' says John. Mrs. Smith is happy now. John likes solving cases like this.
