Girl Power - S4.E3

Carly, a 14 year old girl breaks into The Hive and for some reason Ros is put in charge of her, which she is not too happy about. Beckett is moving into a rather run-down flat which Alex found for him, and his friendship with Ros is rather ‘rocky'. Carly is taken off Ros' hands by a man who turns out to be a baddie after an ancient funeral mask that the Bureau are looking after. He manages to con Carly into stealing the mask and once she realises why they want it, she runs off and hides it. Soon, both Ros and Carly are held prisoner until Carly gives the whereabouts of the mask. They are trapped under a lift. Carly manages to get out and tell Alex and Ed where it is hidden, and they quickly find it.
