Fred examined it, but it didn't look like much of anything except disturbed dust, though something about it was off, and he instinctively moved ahead of Roger to the door, because Fred didn't like letting people move into danger in front of him - if he was going to face shite, he was going to face it head on.

He turned the knob, and it led into a hallway. There was dust here, too, and those same marks. Also, footprints, and they all seemed to lead back through the hallway toward another closed door.
