Bird is a woman on the run. One minute, she's in a meeting in her office in Birmingham - the next, she's walking out on her job, her home, her life. It's a day she thought might come, and one she's prepared for - but nothing could prepare her for what will happen next. As she flees north using multiple disguises, Bird has to work out who exactly is on her trail, and who - if anyone - she can trust. Like many people, she has fantasised about escape for a long time, but now it's actually happening. Is her greatest fear that she will be hunted down, or that she will never be found?
