Piggy In The Middle is the 1409th episode of The Bill.
Luke catches two men trying to commit an arson attack in the dead of night, and it is discovered to be the latest witness intimidation attack to committed by a gang working for Kevin Butcher, brother of Terry Butcher, who is on remand for a brutal stabbing outside a pub. With two out of three key witnesses having been attacked, Kerry is next on the list, and it is not long before she receives a beating at the hands of two masked men. Meanwhile, as Butcher begins to throw his weight around, Meadows realises that Burnside's unorthodox methods have dragged CID straight into the middle of a war with a gang of drug dealers. Then Burnside discovers his main informant may be double-crossing him.
