Avatar: I am Dr. Leopold Avatar. Er, perhaps you've read of me?
Paladin: Hm. Yes, you are Professor Cesare Lombrosso's disciple, and his theory of criminal identification.
Avatar: It is good to meet someone in this country who has heard of our work.
Paladin: Well, I do have a, ah, certain interest in criminology.

Paladin: Yes. They are used to measure what Lombrosso has termed the "stigmata of degeneracy". Certain cranial abnormalities, a low sensitivity to pain, primitive instincts found in cannibals, cave dwellers, apes, animals... and habitual murderers, in short, the mark of Cain.
Avatar: And that is why I have come back to America.
Paladin: Oh, a shortage of murderers in Europe this year?
