The Exorcist1973

Kinderman:
Well, this desecration in the church. Do you think this has anything to do with witchcraft?

Karras:
Maybe. Some rituals use the Black Mass. Maybe.

Kinderman:
And now, Dennings, you read how he died?

Karras:
In a fall.

Kinderman:
Let me tell ya how, and please Father, confidential. Burke Dennings, good Father, was found at the bottom of those steps leading to M Street with his head turned completely around - facing backwards.

Karras:
It didn't happen in the fall?

Kinderman:
It's possible. Possible, however -

Karras:
...unlikely.

Kinderman:
Exactly. So on the one hand, we've got a witchcraft kind of murder, and on the other hand a Black Mass type desecration in the church.

Karras:
You think the killer and the desecrator are the same?

Kinderman:
Maybe somebody crazy. Somebody with a spite against the church. Some unconscious rebellion.

Karras:
A sick priest - is that it?

Kinderman:
Look, Father, this is hard for you. Please, I understand, but for priests on the campus here, you're the psychiatrist. You know who was sick at the time, who wasn't. I mean, this kind of sickness. You'd know that.

Karras:
I don't know anyone who fits that description.

Kinderman:
Ah! Doctor's ethics! If you knew, you wouldn't tell, huh?

Karras:
No, I probably wouldn't.

Kinderman:
Not to bother you with trivia, but a psychiatrist, in sunny California no less, was put in jail for not telling the police what he knew about a patient.

Karras:
Is that a threat?

Kinderman:
No, I mention it only in passing.

Karras:
Incidentally, I mention it only in passing. I could always tell the judge it was a matter of confession.
