The hallway was dimly lit, and she wondered, Is a surveillance camera tracking our every move?

"Shit," Stone announced when they reached the fire door, "it's alarmed."

That's exactly what I was afraid of, she thought.

"Any chance they're bluffing?"

"Don't think so." He pointed. "That little red diode says it's hot."

God, she thought we've got to get out of here. "Maybe we could just make a dash for it?"

He looked at her and shook his head. "Like you're in shape to dash? No, what's called for is stealth."

He was pulling out his wallet. "The thing about these card readers, some of them, like those that get you into bank ATMs, sometimes will open for other cards. I've got four kinds of plastic. Might as well give them a try."

"Well, just hurry." She leaned against the wall. "I'm starting to get weak."

He slipped his Visa through and nothing happened. He immediately tried MasterCard. Again nothing.
