Sometimes the order of events is important, and completing every step can be unclean. If you’ve missed something, try asking for hints and you’ll be pointed in the right direction. Press [LT] or [Space] to ask for help in-game, and you’ll earn an achievement for doing so!

It won’t let me get the letter from the filing, in Farley’s office. Help?

Hmm. To get the letter from the filing, make sure you have read the note from Farley’s Desk. To open the filing cabinet, you’ll need keys from a small table in the same room. To find the correct note in the filing cabinet, look for a card with blue ink and some grease on it.

It sounds like a very tricky puzzle, is this what you’re having trouble with? If not, I’ll keep looking for a solution to your problem.

I see that you can open the safe by inputting J-16-P, but how is one supposed to have figured that out?

@theresa williamson,

The spoon is located on the floor, in the center of the back room. There’s a green rug with bowls scattered around the floor. Try looking straight down and wandering near the bowls to spot the investigation icon.
