"By great Cæsar's immortal ghost!" exclaimed the undisguised tones of Clarence Toxteth at his elbow, "that must be Will Sanford's voice. Where is Patty? Didn't she come?"

"She came, but I don't know where she is."

"I've hunted the whole evening for her, and have had supper put off on purpose to find her before we unmasked. I followed Emily Purdy a while, but I knew her voice the minute she spoke."

The lawyer shrugged his shoulders, but still remained silent.

"For my part," Sanford said, "I shouldn't tell her dress if I knew it; but as it happens I don't. She was covered from head to foot in a waterproof when we came."

Putnam turned away with a feeling of relief. He began to hope that Patty's wild freak might pass unknown, and searched through the rooms, meaning to make a last appeal to her to leave before the masks were removed. His search was of course unsuccessful, but he encountered Emily Purdy.

"How clever Patty Sanford was in deceiving us!" he said as soon as he was sure she knew him. "We might have known she only took that man's dress as a blind. Have you seen her to-night? I think her costume the handsomest here."

"No, I haven't seen her," Emily answered. "How is she dressed?"

"You'll see when we unmask," Tom answered; adding, with quiet sarcasm, "It wouldn't be quite fair to tell before."
