Grim fandango

Love this game. However, it definitely needs a hint area and an overview map. Sometimes I spend a lot of time in the same area looking for the right room or building. I cannot find the letter needed that is supposed to be in Mannys office. I have looked everywhere but to no avail. I cannot proceed without it. If anyone can help, bless you.
