And Then There Were None Hints

Is this weird collection of junk any use?

  • 1 of 4: One thing is useful, one thing is a hint, and the rest is trash.
  • 2 of 4: The microphone can be used on the radio in the other room.
  • 3 of 4: The card has a clue for another puzzle (well, sort of -- like the rest of the cards, it's not that helpful really).
  • 4 of 4: The earring and the document fragment are just garbage.
