There's no time, you idiot! Get in!"
The cool leather of the Rolls's passenger seat engulfs you as you sink down into it. The lady in the driver's seat glances around quickly before turning her attention to you.
"My name is Esme," she says. "Esme Fairfield. Lady Dewsbury, if you want to be all formal about it, but I'd prefer if you didn't. Delighted, I'm sure. Now keep low, keep still, and keep quiet, and we might just get you out of here alive."
With that, Esme starts the Rolls at the first attempt, and its powerful engine growls into life. Smooth as butter, the vehicle pulls away from the curb, onward to your unknown destination.
