Agatha Christie: Murder on the Orient Express Hints

How do I fix the ham radio?

  • 1 of 2: Go look at the radio in room 16 of the Athens-Paris coach. What's missing?
  • 2 of 2: You need a power supply, a telegraph key, and a book on Morse code. (Well, and an antenna, and a license from the FCC, and about six weeks of training, but never mind that now.) I'm going to make these hints more explicit than usual because this set-up is both improbable and ... well, ridiculous. It's not easy to give logical hints to an illogical solution, you know.
