- Please don't stop me. I've got to catch father. The trial...
- Just a minute. Get those words out one at a time so I can understand them, will you?
- Yes, you should know. Somebody's tricked father with this letter.
- Not a word of it's true. It's just to get him out of town.
- Why?
- McCord owns judge Morgan, that's why.
- They've moved the trial up to tomorrow. Morgan will preside.
- And they'll railroad the old man.
- Unless I can bring father back in time.
- Look here, you go on, get back to town.
