Editing City of Death (section)

==Plot==
In Paris, [[Fourth Doctor|the Doctor]] and [[Romana (Doctor Who)|Romana]] sense a time distortion. They observe the Countess Scarlioni using an alien device to scan the security systems housing [[Leonardo da Vinci]]'s ''[[Mona Lisa]]'' at the [[Louvre]]. The pair meet Inspector Duggan, who suspects the Countess to be involved in an art theft scheme with her husband, Count Scarlioni. Duggan joins the Doctor and Romana in investigating the Scarlioni mansion. There, they discover Dr. Kerensky's temporal experiments, the source of the distortions, and six exact copies of the ''Mona Lisa''. The Doctor instructs Romana and Duggan to continue investigating while he returns to the [[TARDIS]] to visit Leonardo. The Count successfully steals the real painting and captures Romana and Duggan after the Doctor leaves. Learning that Romana is familiar with time, he kills Dr. Kerensky and forces Romana to continue the tests.

The Doctor arrives at Leonardo's studio but is captured by another Scarlioni, who reveals he is really Scaroth, the last Jagaroth. His people arrived on Earth 400 million years ago, but the others died when their craft exploded, and his own body was fragmented across time. Collectively, Scaroth's fragments manipulated humanity to invent technology that will let him go back in time to stop the explosion. To finance his work, he employed Leonardo to create copies of the ''Mona Lisa'' to sell off after stealing the original. After Scaroth leaves, the Doctor escapes and writes "This is a fake" on the blank canvases before returning to the present.

Scaroth threatens to destroy Paris if Romana stops helping him. The Doctor tries to gain the Countess' help by showing Scaroth's true form, but Scaroth kills her. Romana completes the work and Scaroth uses it to travel to the past. The Doctor, Romana and Duggan follow him via the TARDIS, fearing that the ship's explosion created life on Earth, and if Scaroth should prevent it, humanity would not exist. Duggan knocks Scaroth out in time, returning the latter to the present, where he is discovered, unmasked, by his bodyguard. The ensuing fight sets the mansion ablaze, destroying Scaroth and the paintings save one marked copy. Duggan argues that they've lost an invaluable piece of art, but the Doctor assures him that the copy, still done by Leonardo's hand, will go unnoticed, and that art is worthless if its monetary value is all that matters before bidding him farewell.
