The class went to the library, but I wanted to find out about Mr Roberts. I always want to find out about things. That’s why I like science. So I walked back to the science room. Miss Kay, the head, was there with another teacher, Mrs Price. I hid outside the door and listened.‘This is very bad,’ said Miss Kay. ‘You know that all the exam papers came from London this week.’‘Yes,’ said Mrs Price.‘And,’ said Miss Kay, ‘no one sees them before the exam.’Mrs Price said ‘yes’ again.‘All the exam papers are in a cupboard in my office,’ said Miss Kay. ‘But this morning the cupboard was open and I looked inside and …’This was exciting, I thought.‘… the science paper wasn’t there,’ Miss Kay said.‘So what did you do?’ Mrs Price asked.‘I came in here. The exam paper was in Mr Roberts’ desk.’I ran back to the library. ‘They say Mr Roberts took an exam paper,’ I told Neesha. ‘That’s terrible,’ she said. ‘But I don’t believe it,’ I said. ‘So we’re going to find out what really happened.’ ‘Don’t be silly,’ said Neesha. ‘We can’t do anything.’‘Yes, we can,’ I said. ‘The head thinks Mr Roberts took the exam paper. But I think someone put it there.’‘But who?’ asked Neesha. ‘And why?’‘That’s what we’re going to find out,’ I told her.
