Suspect No. 1

In Norfolk, an otherwise unassuming summer evening is shaken by an armed robbery; a vehicle is stolen and innocent people are shot.

Detective Inspector Burgess of Norwich CID has a problem as the number of home burglaries has rocketed; looking at the evidence, officers suspect that one man is potentially responsible for a large part of the spike in residential crime.

After a raid on a cannabis factory, nine people are arrested; it is up to the team to get to the bottom of which role each suspect played.

The team in Norwich gathers evidence about a single-punch attack that has left a man seriously injured, with no willing witnesses.
