'I clean the offices and bathrooms and lobby five nights a week, but my actual job is to take care of everyone.They need so much help.'At night, in a corporate office block in an unnamed metropolitan city, the cleaner begins her shift.If she didn't leave everything so spotless you'd never even know she'd been there - but she knows all about you.She knows about the self-help books that Sad Intern hides in her desk, alongside ever-multiplying supplements designed to make her seem less sad.She knows about Mr Buff's secret smoking habit, which she's going to help him kick.She's fond of you all, and she's got more influence over your lives than you could possibly know. And one night, while lazily scrolling through emails on the CEO's computer, she'll discover some shady dealings that put the entire company - her realm - at risk of closure.She has no intention of allowing that to happen.
