Maeve Dunne is a former gossip columnist and a jaded socialite who has recently profited from her friendship with Sarah Bailey. When she is contacted by a prisoner claiming to have new information about Amber, she sees an opportunity to redeem herself.

In an episode viewed through the eyes of DI Dunlop and Sgt Karen Mulcahy, increasingly it appears that Amber's missing mobile phone may provide a definitive answer to the mystery and that a man called Charlie may have that answer.
