9:25pm – Friday, November 12 on ABC1
The identity squad investigate the murder of a wealthy British traveller, Olivia Knighton, in Sydney, hours after which Jane Calshaw (Joanne Froggatt) returns to the UK on her stolen passport.
A game of cat and mouse ensues between the team and the impostor. Jane pretends to be a travelling friend to Olivia’s mother, even going to lunch with her.
When DI Bloom (Aidan Gillen) and DSI Martha Lawson (Keeley Hawes) close in with a wild chase through Knightsbridge shops, she snatches a baby and poses as its mother to elude detection.
Bloom realises they are not dealing with a seasoned identity thief, but a terminally ill woman fulfilling a desperate psychological need rooted in childhood. He peels back the layers of Jane’s past lives and unearths a damaged girl who survived a brutal childhood by locking her sights on a far-off world of metropolitan gentility.
He gets results with an eventual confession, but his methods are unsettling to his team members.
