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 "Blood Money". The original synopsis for the episode was as follows: Part One. Nixon and Noble investigate when a young woman is thrown from a walkway on the Cole Lane Estate, which subsequently leads her husband to try and take his own life. When Smith and Noble attend a disturbance at the woman's flat the next day, they discover that she has disappeared without trace. Meanwhile, an assault being investigated by Webb leads Perkins, Stamp and Casper to go undercover. 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)
