The 18th episode of the radio science fiction comedy series The Hitchhiker’s Guide To The Galaxy is broadcast on BBC Radio, concluding Dirk Maggs’ adaptation of Douglas Adams’ novel Life, The Universe, And Everything with most of the original radio cast. A radio version of the fourth novel, So Long, And Thanks For All The Fish, will follow in 2005. 
Trillian confronts the Elders of Krikkit in a last-ditch attempt to dissuade them from annihilating the universe with the Supernova Bomb, and she and Arthur confront HACTAR, the computer intelligence that not only isolated the planet Krikkit but drove its people to the brink of a bloodthirsty paranoia. Thanks to Marvin’s connection to Krikkit’s central battle computer, the robot army has become not just ineffectual, but too depressed to wage war. Somehow, the unlikely assemblage of galactic hitchhikers may actually save the universe – and along the way, Arthur discovers an even more improbable opportunity to find out about the ultimate question to which “42” is the answer.
