The twelfth series of The Bill, a British television drama, consisted of 156 episodes, broadcast between 2 January and 31 December 1996. On 6 February 2013, The Bill Series 12 Part 1 & 2 and The Bill Series 12 Part 3 & 4 DVD sets were released (in Australia). The show aired the death of PC Cathy Marshall early in the series, actress Lynne Miller departing after seven years in a mysterious plot that saw her drown whilst chasing a suspect, but it was never confirmed if she was pushed or slipped off a riverside barge during the pursuit. The death followed that of DS Jo Morgan in a four-part special towards the end of the previous series, with the first three of the four episodes rebroadcast in the summer as part of a single special episode; Target.
