Mr. Frederick does turn and look, but he snaps back to attention soon enough to close the door after him and cut off the escape path. He slams his hand on the lightswitch and the whole room lights up.

Howard tries to sink further behind the bin, but Mr. Frederick reaches down and grabs him by the upper arm, hauling him up. "I've already called the police on you! You think you can bring your little girlfriend with you and steal my things and maybe snog her in my store room after hours? Is that what you think?"

He drags Howard in front of the door, so Diana can't get out either. Howard twists and thrashes like a cat stuck in a trap, yelling something or other, but whatever it is it'd make most people's ears turn white.
