Twenty-six-year-old Maggie Barnes is someone you would never look at twice. Living alone in a month-to-month sublet in London, with no family but an estranged sister, no boyfriend or partner, and no friends, Maggie is just the kind of person who could vanish without anyone taking notice. Or just the kind of person MI5 needs to thwart an international plot that puts all of Britain at risk. An ingenious standalone psychological thriller.
