And Then There Were None Hints

How do I open the safe?

  • 1 of 3: Remember the coded note in Marston's room?
  • 2 of 3: That combination is now in your notebook, under "General." Look it up.
  • 3 of 3: To use it, press the left arrow on the screen till it reaches the first number, then press the right arrow till it reaches the second number, then the left arrow to reach the third number. You don't have to go past the number, as you do in a real safe.
