The Big Sleep1946

Vivian:
So you're a private detective. I didn't know they existed, except in books. Or else they were greasy little men snooping around hotel corridors. My, you're a mess, aren't you?

Marlowe:
I'm not very tall either. Next time, I'll come on stilts, wear a white tie and carry a tennis racket.

Vivian:
I doubt if even that would help. Now this business of Dad's. You think you can handle it for him?

Marlowe:
It shouldn't be too tough.

Vivian:
Really? I would have thought a case like that took a little effort.

Marlowe:
Not too much.

Vivian:
What will your first step be?

Marlowe:
The usual one.

Vivian:
I didn't know there was a usual one.

Marlowe:
Oh sure there is. It comes complete with diagrams on page forty-seven of 'How to Be a Detective in Ten Easy Lessons' correspondence school textbook.
