Odd noises

After the women leave you take a few minutes to get some things together before turning your light off and shutting your door. The office is quiet, everyone else long since gone home. You're heading for the front door when you hear the noise of a drawer sliding shut from one of the offices. Curious who is still here, you walk towards where you heard the sound. You start to hear other noises, a sudden clatter of small objects, and another drawer shutting.

The noises come from Jim Gavin's office. You know he had a dinner meeting with a client, so you wonder who is in his office. As you tell yourself it's probably the cleaners, you peer around his door to look.

At first you see nothing, but then you notice the top of someone's head behind the desk. They appear to be looking at something out of your sight. You're about to speak when you notice that there is a bottle of bourbon on the desk. A bottle of very expensive bourbon you've seen several times in Jim Gavin's liquor cabinet. A glass with about a finger of amber liquid sits beside it.
