Sorry, Geoff, I meant to come back to it.
After reading deb's reply I just thought I'd have a play with 2nd p using your scenario of an amnesiac, as I was having dificulty envisaging it from the pov of a peeping perv.

Good synopsis, by the way.

I was having dificulty envisaging it from the pov of a peeping perv.

I can see you. I can see you as you move the flimsy curtains aside and stretch in front of the window, your body sinewy in the cool morning light. I see your flat stomach and the curve of your unfettered breast as you touch your toes and turn your bottom to the sky, the blood rushing to your head.

I do wish you could withdraw msgs. I am a total idiot. Yes, I KNOW that isn't in 2nd person. Just rattled it off for fun without engaging brain!

But you could do something very similar in 2nd p.
