I liked the links, but "murder" is not accepted for the christie/poirot group and "Adams" was not accepted for hitchhiker group. Shame

Got me thinking though...thanks

Not bad - eclectic mix. Personally, no chance of getting the Hollywood or Cabin Fever answers! I agree that Adams should have been accepted. And, my pedantic side would like to point out that there is no Murder to remove from Curtain! Thanks for setting.

I also put Adams as the link as it seemed a short concise way of saying I knew the group, but technically And Another Thing isn't written by him so I can forgive the puzzle setter for that.
