The mastertape of this episode was stolen during a robbery at the programme's recording studios in September 2006. Subsequently, filming schedules did not allow for the episode to re-recorded in time for broadcast. Subsequently, this episode would later be re-written and re-titled and broadcast during Series 23 under the title of "To Honour and Obey". The original synopsis for the episode was as follows: Part Two. Nixon and Meadows investigate when the body of Reshna Dewan is hauled from the Thames, and new evidence suggests that her extra-marital affairs may have had a part to play in her death. Meanwhile, Noble and Webb question the eccentric victim of an alleged mugging, who claims to be an undercover police officer, but Scotland Yard refuse to confirm or deny whether or not she is telling the truth. The initial recording would not have featured Sgt. Nikki Wright (Gillian Taylforth), and this appears to be the only character re-write in the second recording. (thetvdb.com)
