“Who?” demanded Darley.
“—Joseph Darley,” declared The Shadow.
“Prove it!” came Darley’s challenge.
“I can prove it,” said The Shadow, “because I know the secret of Green Eyes!”
AS Darley stared, the man who looked like Foy closed his eyelids. Yet the eyes still seemed to be open! They were gazing, with livid, flashing green, directly at Joseph Darley!
The green eyes vanished. In their place were the eyes of The Shadow. Stern, unyielding eyes — more powerful than those weird flashing optics of green!
“I know your simple secret,” said The Shadow. “I learned it the first time I saw you as Green Eyes.
“Not your eyes, Darley, but your eyelids, sent those sparkles. Two flat, green stones, attached to your eyelids. They caused that sinister sparkle that has deceived your companions.
“Your green eyes were amazing, Darley, when you looked at your followers. They did not know that your lids were closed, not open, when that strange gaze made them quail.”
As if to emphasize his statement, The Shadow closed his eyelids. Again, that amazing flash of insidious green. But to Darley, that glow meant opportunity — not menace.
