The Demon of Paris ( audio story ) The Demon of Paris was the second story in the Demon Quest arc , a series of five audio dramas featuring Tom Baker as the Fourth Doctor . Publisher ' s summary . Someone has painted the Doctor ' s likeness into a famous poster by Toulouse - Lautrec , leading Mrs Wibbsey and him to Paris in the 1894 . The streets are thronged with artists and their muses – ladies of the night such as the young girl La Charlotte . But a murderer is also at large , and Lautrec ' s name is whispered with fear and suspicion . As they become immersed in the delights of the Moulin Rouge and the shadows of Montmartre Cemetery , the travellers gradually uncover the gruesome truth about the missing women of Paris . They also realise that someone has been expecting them . . . Plot . Based on another clue from the bag left at the church sale in " The Relics of Time " , the Doctor and Mrs . Wibbsey travel to Montmartre , Paris , 1894 ( being obligated to travel via train from Surrey , as the TARDIS still can ’ t travel in space ) . The clue is a Tolouse - Lautrec poster of Aristide Bruant which has been “ doctored ” ( pun intended ) to feature the Fourth Doctor ’ s face — and portrays him holding a piece of the spatial geometer . He immediately meets a girl calling herself La Charlotte , and buys her dinner while seeking information . The crowd thinks the Doctor is Bruant , who is missing and presumed dead ; they want him to sing . They have arrived in the middle of a mystery , much to Mrs . Wibbsey ’ s dismay . While the Doctor is occupied , Wibbsey meets a drunken man who insists that Lautrec , the artist , is responsible for not only Bruant ’ s death , but also many other murders — dozens , as La Charlotte mentions — many of which are young women of ill repute . Lautrec is not unaware of the suspicions , and has isolated himself . La Charlotte leads the Doctor and Wibbsey to Lautrec ’ s home , then leaves them . The concierge grudgingly lets them in , and they check Lautrec ’ s studio — but it is empty , Lautrec missing , with the skylight smashed and sketches everywhere . Alarmingly , many of his paintings — many of which are famous in the future — have been defaced , slashed at the wrists and necks of the subjects , and with red paint splashed on like blood . They leave and return to Montmartre , seeking out the worst part of town , and find the Moulin Rouge dance hall . Inside , the Doctor sees Lautrec enter . The Doctor quizzes Lautrec about the poster , but Lautrec denies having painted it , claiming it was vandalised by someone else . He is unhelpful , but comments that La Charlotte and the other girls should look out for themselves ; but he denies being the killer , and claims the public wants him as a scapegoat . Lautrec rids himself of the Doctor by telling the crowd that the Doctor is Bruant , forcing him to sing ( badly , but hilariously ) . Lautrec leaves , and Wibbsey follows him . Lautrec detects her , and confronts her . She is captivated by him , and frightened ; while she is dazed , he asks her to model for him . Again , he denies hurting anyone , and mentions wrestling with his demons . Reluctantly she goes with him , leaving the Doctor searching for her . The Doctor is intercepted by a drunken La Charlotte , who is bleeding from several stab wounds ; she hints that Lautrec caused them , in the nearby cemetery . She is disbelieving that Lautrec could do it , but is certain it was him , though she never saw his face , due to the smell of the absinthe that he had been drinking . She takes the Doctor to the cemetery to show him the scene of the attack ; he thinks that Lautrec and Wibbsey are there , but is wrong ; they have returned to his studio . Lautrec is shocked at the destruction of his art . Lautrec denies that he destroyed his work , and denies that he hurt La Charlotte earlier in the night . When the concierge exits , he admits that he has blackouts . At the cemetery , the Doctor and La Charlotte meet the concierge coming down the hill , and the Doctor notices an odd green glow as she approaches ; the woman insults La Charlotte and drives her away . The Doctor is angry , but the concierge mentions that Wibbsey is with Lautrec at the house ; she tries to divert the Doctor , but he insists on returning there . At the house , Lautrec busies himself preparing to paint Mrs . Wibbsey — but suddenly they both notice a piece of the spatial geometer on his desk . She accuses him , but the Doctor arrives at that moment with the concierge . Lautrec insists again that he did not hurt La Charlotte ; but the concierge breaks down and says she has covered for him . She takes them to the attic , where he says he has never been ; a dozen or more desiccated bodies of young women are there . The concierge and Lautrec leave , locking the Doctor and Wibbsey in . Trapped , they take a moment and look at another item from the sale bag : a book of fairy tales . One of the illustrations , of an ice monster , contains the images of the Doctor and Mike Yates ; it seems that Yates is part of this mystery as well . La Charlotte rescues them , and says she saw Lautrec and the concierge leaving . Lautrec left in a carriage , but the concierge is at the cemetery ; it seems she is more involved than the Doctor thought . The trio rush to the cemetery . Arriving there , the Doctor suddenly realises that La Charlotte ’ s wounds don ’ t seem to be troubling her anymore ; he confides to Wibbsey that the girl may have been faking . The green glow can also be seen again , near a small mausoleum . They find the concierge on the ground , and she claims that Lautrec came back to attack her , but pulled back at the last second . She claims Lautrec is inside the tomb . When Lautrec calls out for help , Wibbsey darts inside … and finds herself in the mosaic - lined chamber from Claudius ’ s hut in the preceding story . Lautrec is tied in the floor , but the Doctor frees him . The concierge drives them back inside , and activates the chamber ; the Doctor and Wibbsey try to stop the door from sealing , and La Charlotte joins them . The concierge kills La Charlotte by sapping her life force . The Doctor explains to Lautrec that the concierge is a shapeshifter and an alien , who has framed him while carrying out the killings . She admits it , and says that they can now depart . Lautrec attacks the concierge , giving the Doctor and Wibbsey enough room to lever the door open , allowing the three of them to escape . As they do so , the mausoleum vanishes , as it did from the tribal hut before . The Doctor thinks La Charlotte was killed some time ago , and kept alive just as a slave . The bodies in the attic will disintegrate , and Lautrec will be free of suspicion ; he can also try to find the real Bruant . The Doctor urges him to forget it all , and to plead ignorance . Back at the TARDIS , the Doctor and Mrs . Wibbsey arrive back at Nest Cottage on the same day they left , December 23 , 2010 . They have just enough time to prepare a bit for Christmas , when Yates ( and his hound , Captain ) arrive . The Doctor admits they have enough time for dinner … and then they must get back on the case . Continuity . " to be added "
