Agatha was in the library, reading the Girl Detective series, when she noticed something strange. Her best friends, Timmy and Florence, were talking to each other in whispers while keeping a good, safe distance from her! When she waved at them, they looked away.
Things only got stranger in art class. Timmy and Florence went to sit at a different table from Agatha busy painting and glanced at her when they thought she wasn’t looking.
Now, Agatha considered herself to be something of a detective. After all, she had read many detective stories for children and even had an old broken magnifying glass(放大镜)abandoned by her father. When the rest of the class went out for lunch, she slipped to Timmy and Florence’s table and examined it carefully with the magnifying glass.
There was paint, and red and pink construction paper. What could they be doing? This was definitely a mystery that needed solving!
After lunch Timmy and Florence chatted to her as if nothing was going on, but they kept smiling at her in a slightly strange way. Of course, Agatha could have asked them what they were up to, and they might have told her -but she wouldn’t have a chance to become a detective!
On the way home from school, Florence and her mum happened to walk ahead of Agatha and her mum. Agatha saw them go into the bookshop. Strange, again. Florence didn’t read much—no matter how many detective stories Agatha recommended to her!
The next day at school, Agatha kept an eye on her friends and tried to work out their mystery, but they seemed determined to keep things secret. She asked them if they would like to play with her after school, but they said they couldn’t because they were busy. Even more mysterious…
When Agatha’s mum came to pick her up after school, she was so lost in the unsolved mystery that she hardly noticed her busy father was coming along, which was unusual. When they arrived home, her father said she could go into the living room.
