Quote context

[...]

- That's the right answer. Now you're really taken care of.

- In what manner, if I may ask?

- Sanderson's got a letter I wrote. If I'm not back at the hotel by 11:15, to collect it myself, he's to call the police department, and turn it over to them.

- Are you going' for that garbage?

- And just what does this fascinating letter contain, Mr Murdock?

- Evidence.

- Evidence that a couple of cheap guns named Martinelli and Krause knocked off Johnny Preston on the Tarpon Springs Road.

- Correct me if I'm wrong.

- Take Mr Murdock to the Hotel Southern.

- Walk arm in arm with him, like the best of friends, with your hand on the gun in your pocket.

- Go directly to the elevators, our bruised guest's hat well down over his face.

- Mr Murdock will call the manager, and tell him to bring the letter up to his room.
