Swan, however, was not troubling himself over what Lone would think, or even what Warfield was thinking.

Swan had made a mistake, and he was humiliated over his blunder.

Al had kept himself so successfully in the background while Lone's peculiar actions had held his attention, that Swan had never considered Al Woodruff as the killer.

Now he blamed himself for Frank's death.
