Safecracker - Hints From Sue (plus one from Jenny) To open the voice safe in Customer Support (Room 11), examine the letter tray on the desk to find a Dictaphone. Play this tape to the safe to open it. In the music room, play the tape recorder to hear 'Twinkle Twinkle Little Star' then play it on the piano, starting from G below middle C. To get into Crabb's Office, ignore the touch pad. You get in through the library. Examine the books near the window (by the 'do not pull' sign) to find a secret way in. In the secret room (Room 10), the code for the display is O-P-Q-N in that order. With the safes that take 3 keys, Jenny says, don't put just some of them in; wait until you've got all 3 because the other 2 will disappear and you won't be able to finish the game! - o -
