as his eyes follow marty's exit. the bathroom door doesn't close all the way; a narrow shaft of light slices the office from the bare bulb in the bathroom.
staring at marty.
as he reaches into his breast pocket and withdraws a handkerchief. he wipes his forehead, then picks up the gun and wipes it off. he leans down with the gun.
as he slowly, quietly draws his hand in from the hole in the wall. he is holding the knife.
moving quietly toward the door.
