Logopolis

TV Season 18, Serial 7

Aired: 28 February 1981 - 21 March 1981

The final Fourth Doctor story. The Master finally gets to kill the Doctor (more or less), as well as Tegan's Aunt Vanessa, the entirety of Logopolis, and a good chunk of the whole freakin' universe. Again, you'd think that would come up more often than it does.
