Fourth Doctor

The Fourth Doctor, commonly referred to simply as "The Doctor", was the main character in the BBC television series Doctor Who. Played by British actor Tom Baker, this version of the perpetually regenerating Time Lord was introduced in an uncredited appearance in the final chapter of the 1974 serial "Planet of the Spiders". Baker served in the capacity of the Doctor from June of 1974 to March of 1981, appearing in a total of 173 episodes, comprising 41 story-arcs. The first serial to fully feature the Fourth Doctor was "Robot", which ran from December 28th, 1974 to January 18th, 1975. His final turn as the Doctor was in Logopolis, which ran from February 28th to March 21st of 1981. Tom Baker's Doctor was preceded Jon Pertwee, who played the Third Doctor in 124 episodes, and he was succeeded by Peter Davison who played the Fifth Doctor from 1981 to 1984 (70 episodes in total). Baker's iteration of the eponymous hero is arguably the most famous and recognizable version of the Doctor, characterized by his dry sense of humor, animated, wide-eyed facial expressions, his wide-brimmed fedora and his long, flowing coat and scarf.

City of Death
The Doctor and Romana traveled to Paris, France on holiday, but immediately became aware of an apparent time slip that was localized to the area. Investigating further, they discovered that the time slip was being caused by an ancient alien named Scaroth - last of the Jagaroth species, whose physical essence had been splintered into twelve different aspects and scattered across the time stream. The present day aspect of Scaroth had disguised himself as human and went by the name Carlos Scarlioni. He had succeeded in stealing the Mona Lisa from the Louvre and used the money to finance the creation of a time machine that could send him back into Earth's primordial past so he could prevent the accident that fractured his physical being. Doing so however, would have prevented the development of life on Earth, so the Doctor, Romana and a private investigator named Duggan used the TARDIS to follow Scaroth back in time and stopped him altering Earth's history.
