Children's spy drama. The Head of M.I.9 and Stark summon the team to their office. Something big has happened. Jade Dixon Halliday has sent an urgent plea for help: her cover is blown within SKUL and she needs to be broken out. Oscar is incredulous, believing she's not on their side and that she works for SKUL and is trying to trick them. Surely Operation Flopsy should have confirmed that? Unfortunately for Oscar, the evidence suggests she's telling the truth. A mole within SKUL has leaked information to M.I.9. Oscar's mum is the mole and he won't accept the mission. Rose, Carrie and Frank decline as well, and they stand by Oscar's decision. The resurfacing of his mum has disturbed Oscar - he wants nothing to do with her, and he is the only one who knows just how dangerous she is. After much deliberation he decides that if he doesn't accept the mission, someone else from M.I.9 will be sent, and this concerns him.
