Let's just go with regular comic.
A hand has just pushed a key into a deadbolt lock.
A badly-lit apartment building hallway-- there's a hint of daylight from a window at the back. Sam is standing in front of that open door-- he's looking through his mail.
We're inside the apartment before Sam, looking through the open doorway into the bedroom. All we can see is the corner of the bed and a pair of old shoes-- and a human shadow falling onto the floor at the middle of the room.
We're still inside the apartment, and now so is Sam. Motion lines around his left foot show us he's just kicked the door shut. More motion lines run from his right hand to the mail having just landed percariously on a mock foyer shelf. Obviously, our boy is NOT in the bedroom.
A refrigerator door blocks our view of the rest of the kitchen as Sam drinks OJ from the bottle. Safe and sound at home!
Same shot as panel 3, looking into the bedroom. That shadow is closer to the open door. Uh-oh.
Sam's living room. A couple of curtained windows-- curtains drawn. Sam is behind the sofa, looking at his tv remote-- our POV being where the TV would be from another angle. That open doorway-- lots of shadows, and the slightest hint of the shape and color of a human hand at the right level. A bookcase-- a holstered gun on top.
A much bigger hand than Sam's has just brushed against the bedroom door.
A profile of Sam-- the look of a man who thinks he may have just heard something unexpected-- but our focal point is Sam's ear-- because he HAS heard something.
Right on Sam's face-- his eyes gone a little wide. Not so safe and sound!
The holstered gun on the shelf.
The shadowy-shape of an indistinct but very large man in the bedroom doorway. Sam has just turned and jumped for his gun--
