How the clue works
A novel quote is the definition — it's the title-line farewell from the fourth Hitchhiker's Guide book by Douglas Adams. The wordplay is an anagram (indicated by "Liquid") of "Flash Gordon in on the talks" together with a second "Flash", and those 28 letters rearrange neatly to give SO LONG AND THANKS FOR ALL THE FISH.
