‘Hey,’ cried a voice from behind the toilet door. ‘I’m in here!’ ‘Oh sorry,’ replied Emma. ‘No problem, take your time.’ Emma waited, feeling slightly fidgety. She needed to get to the Mission Tube—quickly. The Mission Tube was the secret network that took SHINE agents to the Code Room and then on to SHINE HQ for mission briefings. It was very clever—and very fun—but Emma wished it didn’t have to start in the toilet block. It was a bit gross. The toilet flushed and then an older girl came out. At last! ‘Thanks!’ said Emma. ‘What’s wrong with the other six toilets?’ asked the girl. ‘They’re all empty.’ ‘Yes, but ... but...’ But what? ‘But I like this one.’ Groan. ‘Er, okay,’ said the girl, looking at Emma as if she was a bit strange. ‘Whatever.’ Whatever indeed! Emma rushed into the cubicle and locked the door. She put down the toilet seat, sat down and flipped open the toilet roll holder—and Mission Tube access pad.
