Los Chimpos Ride Again

You inspect the desk.

The reading lamp seems to work but you find the telephone is dead when you pick it up; there is no dialing tone and some of the numbers seem faded.
Standing, ignoring the rolled paper for now, you move to the filing cabinet and try to open the first drawer.
It is locked.
You try the middle and bottom drawers but, again, they will not open.

You pick up the small box and shake it. You hear a gentle rattling.
Turning, bringing the box with you, you move back to the table and sit down.
