Secret of Arkatron ( short story ) Secret of Arkatron was a short prose story published in August 2010 by BBC Children ' s Books . Summary . The Eleventh Doctor and Amy Pond arrive on a barren asteroid with a breathable atmosphere and find a large spooky looking house ( complete with Gargoyles ) , high on a plateau . Exploring the run - down house , with remnants of the word " Arkatron " inscribed above the door , the house appears to be empty and abandoned . Inside they find the walls lined with picture frames that , on detecting , play a series of videos that features military generals giving speeches , overlooking battles or some sort of ceremonial occasion but all without sound . The Doctor becomes distracted when he discovers loose wires and finds that defences to the house seem to have been disabled and judging by the footprints in the dust – recently ! After more exploring and a scare for Amy , they meet two others in the house – Miss Crisp and Professor Landale . Having recently arrived themselves , Crisp and Landale claim salvage rights to the house and it was them that disabled the house defences . The early notion that the house was a museum or gallery is dismissed when the Doctor points out that everything is off the same period . When one of the suits of armour is reactivated and attacks Amy , the Doctor uses his sonic screwdriver to deactivate it and discovers a hidden room that the suit was guarding . Inside the room they find an empty bed in the middle of the room with a rolling screen of names at the foot listing the names with the screen headed with the words ' Lest you forget ' . More suits of armour stand around the room and from the shadows creeps an unremarkable looking man who demands to know who the newcomers are . The man introduces himself as Lester Forge , the Curator of the Museum of the Ninth Dynasty of Arkatron – a bloodthirsty regime during the time of the dictators . While Crisp has a look around the body of an elderly woman falls from a cupboard and slumps to the floor . Lester recognises the body and says it was his assistant Miss Dellman . As Lester asks what ' s going on , the Doctor turns to Amy and says he knows exactly what ' s been going on and is surprised Amy hasn ' t picked up on the clues . . . . . . The Doctor pieces together the library ( full of court reports and records of the atrocities and a trial ) , the videos ( a record of the Ninth Dynasty of Arkatron ) , and most significantly , in all the backgrounds the figure of a bald little man with glasses shown in some of the videos being led away in chains through the house that would be his prison – Lester Forge ! ( a name taken in a hurry from the words above the names of the dead ) . Suddenly pulling out a weapon , Lester reveals himself as the war criminal Maxim Klart – the real power behind disappearances and killings . Trapped in a stasis bed for years and forced to watch the names of his victims , when Crisp deactivated the house ' s security she unwittingly released Klart who turned on his warden Miss Dellman and killed her . Armed , Klart demands access to a spacecraft that he can finally escape and take more lives . Believing the Doctors sonic screwdriver to be a means of unlocking his spaceship , the Doctor instead uses it to repair the house ' s security system and once back online , the suits of armour are reanimated and over - power Klart , forcing him back into stasis on the bed . With Klart once more imprisoned , the suits of armour return to their positions and Crisp , Landale , Amy and the Doctor together deciding that the most respectful thing to do is to walk away and leave the place as they found it .
