With me dead, their precious secret will be safe.

You're going to an early grave with your precious secret, Nicholas.

But they needn't worry so much about giving away their precious secret.

And also he who gave away the precious secrets to the white man.

You can't even go down there and be their friend because that might jeopardize your precious secret.

And he must not throw away his most precious secret there.

Truth be told, precious few secrets went to the grave with anyone.

This suggests great confidence that he will protect his group's most precious secrets.

A perfect example is that investment bank whose most precious secrets he was able to learn in only a few days.

"Nature has revealed to us the precious secret that light is an attribute of a field - an accident, as people used to say."
