Repeat Offender ( audio story ) Publisher ' s summary . The Doctor has tracked the deadly Bratanian Shroud to 22nd century Reykjavík – where he ' s about to become the victim of a serial criminal . Again . Plot . Lara Jensen returns home to find a smell of burning in the air and two strangers standing over the unconscious body of her wife , Kat Gunnarsdottir . One of the strangers introduces himself as the Doctor and explains that they have just saved Kat from a creature called the Bratanian Shroud and that the burning smell is from a mediascreen which he adapted to use as a wave disruptor . Lara whips out her chem - spray , points it at the strangers , and calls the police . The other stranger , Turlough , asks to go to the lavatory , pointing out that there is only way out of the apartment . Shortly after Lara agrees , this is no longer the case . Turlough uses a laser to make a hole in the washroom ' s wall and then climbs to the ground . At this point , Police Inspector Jill Sveinsdóttir arrives on the scene . Sveinsdóttir scans Lara and the Doctor and finds that the Doctor is an unregistered visitor to Iceland , a crime punishable by 2 years in jail . Sveinsdóttir presses some controls on her uniform and begins the Doctor ' s trial . Accused of breaking and entering , assault , destroying private property , and illegal immigration , the Doctor can only say that he ' s " not exactly guilty " . He tries to explain that he was there to stop an alien evil from committing murder , but Sveinsdóttir opens Kat ' s perception feed and sees the Doctor threatening Kat with a weapon . The Doctor insists that the footage has been tampered with . After a bit of research , Sveinsdóttir notices that two similar events occurred in the block in the last five weeks . The other two both involved broken mediascreens , residents knocked unconscious and suffering amnesia , footage apparently being tampered with , and a charred body in the doorway . Further research finds that a total of eight similar deaths have occurred in the surrounding area . While the Doctor tries to convince the Inspector that this is further evidence of the danger posed by the Shroud , she asserts that he must have committed all these murders and that " he " was planning on tampering Kat ' s perception feed before getting away . Then , Turlough phones Lara . When she puts it to speaker , he tells the Doctor that he has found three different versions of the TARDIS and then hangs up . Alarmed , the Doctor asks Sveinsdóttir some questions about the victims . He learns that all of them were burnt beyond recognition and had two hearts . The Doctor insists that he ' s caught in a paradox ; his own future selves did the exact same things he ' s doing now and were killed . Sveinsdóttir tries to take him out of the flat , but the Doctor realises that the other Doctors each died as they left the apartments and that he too will be killed if he enters the doorway . As a last defence , the Doctor pleads that Lara come closer to the mediascreen . Lara attempts to resist , but Sveinsdóttir forces her to come over . Within the range of the mediascreen ' s wave disruptor , Lara collapses , the Shroud free from her mind . Sveinsdóttir is almost convinced of the Doctor ' s story , but Turlough walks into the flat and says that he and the Doctor are responsible for the killings . The Doctor sees that Turlough is obviously being controlled by the Shroud and deduces that the Shroud must be using Reykjavik ' s wireless data transfer system to move between any body in the city . If the Shroud were stranded without the system or a brain to inhabit , it would dissolve into nothing . The Doctor orders Sveinsdóttir to use her root access to Reykjavik ' s data flow to shut it down . She is slightly hesitant , but comes to see the threat that the Shroud poses and obeys . The Doctor then runs towards Turlough with the mediascreen , purging the Shroud out of his mind and killing it . As the Doctor and Turlough begin to leave , Sveinsdóttir asks them to testify for her during the inevitable investigation of such a vital system being disabled . The Doctor assures her that when he encounters the Shroud a few weeks ago he will defeat it , meaning that it will never live to possess Kat Gunnarsdottir and Sveinsdóttir will never have even met them .
