After solving the floorboard puzzel

I got the small key for the kitchen and now I need to speak to Katarina regarding the item from Adam's apt, but she doesn't answer the door. Now what, there's nothing else do do>Please Help!!!

Hi,

My experience is that if the next 'phase' doesn't show up, it means there's something still missing.

If you're unsure what you missed, I found the best solution is to start over.
Let us know how you make out

Use the key on the clock in the kitchen.........

how do you solve the puzzle box in the floorboard??? i've been going round n round in circles
