Shadow of Death ( audio story ) Publisher ' s summary . Following an emergency landing , the TARDIS arrives on a remote world orbiting a peculiar star – a pulsar which exerts an enormous gravitational force , strong enough to warp time . On further exploration the Doctor and his friends , Jamie and Zoe , discover a human outpost on the planet surface , inhabited by scientists who are there to study an ancient city . The city is apparently abandoned , but the scientists are at a loss to explain what happened to its sophisticated alien architects . The Doctor discovers that something dark , silent and deadly is also present on the world - and it is slowly closing in on the human intruders . . . Plot . The Second Doctor , Jamie , and Zoe find themselves on a planet orbiting a pulsar in the year 2724 . The pulsar ' s gravitational pulses are strong enough to the drag the TARDIS out of its flight , leading it to be at least temporarily stuck on the planet . Things are not as they seem . They find themselves in a human base built near an ancient city . Looking out onto the surface , the Doctor and his companions see what appear to be statues of figures in spacesuits . The Doctor and his companions are quickly captured by more humans , who prove to be part of a galactic survey expedition , led by Dr Sophie Topolovic . Although there is mutual suspicion at first , it quickly turns to an alliance of necessity when it becomes clear that they are not alone . A shadowy being — or possibly more than one — is also roaming the corridors of the base ; and its touch is death . Zoe explains to Jamie that the statues are more of Sophie ' s crew , but moving much more slowly outside , which the Doctor realises is because of the gravitational forces of the pulsar : while just minutes might pass outside , it would be weeks in the base . After much misdirection and danger — both from the shadow and from the gravitational pulses — the Doctor finds himself isolated , and attempts to get to the TARDIS and escape the city , then recover his friends . However , he is stopped by an odd visitation . The Eleventh Doctor , from far in his personal future , makes psychic contact with him ; he sees the Eleventh Doctor ' s image and that of his psychic paper , which spells out written instructions . He must not only save himself and the others , but must also save the survey team ' s work ; it will be vital in the future . Resigned , he forgoes the TARDIS and returns to the control room to save the data . . . and is captured by the shadows . Hours later , the Doctor rejoins Jamie and the others . He explains that the shadows are the indigenous , intelligent species of this world ; he refers to them as the Quiet Ones . He explains that their world was once a rogue planet , without a star ; Jamie compares them and their situation to the Cybermen of Mondas , which was also a sort of rogue planet . The Doctor states that their world was captured by the pulsar ; to protect themselves , they transformed themselves into a non - corporeal form which exists at a much higher rate of time than humans . The deaths were unintentional , caused by the colliding of different time zones ; they were attempting to make contact , not kill . The problem , it seems , is the noise the humans make ; the Quiet Ones are highly sensitive to sound , and need a quiet environment to live . All they really wanted , it seems , was to get the humans to " keep it down " . The Doctor has brokered a truce which will allow the research to continue . Jamie , however , realises something is amiss . He asks why the Doctor was not killed when touched ; the Doctor attributes it to his relationship with time , which is different from that of the humans . Still , he has aged a bit ; and under pressure , he reveals that while Jamie and Zoe only experienced a few hours on the planet , for him , it was a few years .
