Surprise Surprise

With a five-year-old girl in hospital having accidentally ingested crack cocaine, the search is on to find her mother—and it's not long before Sgt Matt Boyden realises the missing woman is none other than his own tearaway daughter Amy. But the case takes on a different dimension for PC Gary Best when he discovers that colleague PC Nick Klein was also in the taxi that dropped the little girl off. Back at the station, a thief is at large and new boy PC Cameron Tait is in the frame, while Acting DI Sam Nixon faces facts when her trouble-making teenage daughter is brought in for being drunk and disorderly.
