Donating blood time again

Nurse: I'll just swab here and paint your arm a lovely shade of yellow.
Nurse: *gets out needle*
Me: *looks firmly in the other direction*
Nurse: There! All done!
Me: That was very smooth!
Nurse: Thank you - I notice you looked away.
Me: I never look.
Nurse: Oh I don't either!

Quicksand by John Brunner

A beautiful girl is discovered naked near a mental hospital, she speaks a language no one understands and she quickly becomes an obsession to one of the psychiatrists there.

The plot seems to be about P.F. the psychiatrist having to question everything he knows to be real as his undeniably intelligent patient slowly reveals herself to be neither insane nor from this time. By today's standards he is most definitely a loony himself and I'm inclined to read this as a descent into madness as the patient is revealed to be ultimately sane and her therapist a man with serious reality problems that culminate in crisis. Or it was written in 1969 and P.F. is supposed to be a normal man driven to the brink by an insane contradiction.
