"You've got your chance. Speak out."

I told it carefully. The details of it grew with my words. Jetta joined in it. But, most of all, it did indeed sound feasible. "But it must be done at once," I urged. "The weather is right; to-night it will be dark; overcast; not much wind. Don't you think so?"
