"It needs no proof. I tell you so."

The flashlight exposed the ugly confidence of Robinson's smile.

"I am sorry to suggest the need of corroboration."

"You doubt my word?" she flashed.

"A woman," he answered, "has obliterated valuable testimony, I shall make it my business to punish her."

She laughed again. Without another word she turned and reentered the house. Robinson's oath was audible to the others.

"We can't put up with that sort of thing, sir," Rawlins said.

"I ought to place this entire household under arrest," Robinson muttered.
