Whatever you do," and he addressed Harry, "say nothing about what you were telling me this afternoon.

In the first place, you yourself have no actual knowledge of what happened.

How do you know but what Thornton Fairchild was attacked by this man and forced to kill in self-defense?
It's a penitentiary offense for a man to strike another, without sufficient justification, beneath ground.

And had Sissie Larsen even so much as slapped Thornton Fairchild, that man would have been perfectly justified in killing him to protect himself.
I 'm simply telling you that so that you will have no qualms in keeping concealed facts which, at this time, have no bearing.

Guide yourselves accordingly--and as I say, I will be there only as a spectator, unless events should necessitate something else." They promised and went on, somewhat calmer in mind, to edge their way to the steps and to enter the basement of the courthouse.
