"Go on," said Ariston. "Of whom are you thinking?"

"A veiled woman passed out that day and put a piece of money in my hand."

"Over-astute Neaera!" thought I.

"Did you not recognize the woman?" asked Ariston.

"No, she was veiled."

"Would you be surprised if I could guess at what hour she passed out?"

The janitor looked at Ariston stupidly.

"She passed out within an hour after Lydia."

"Yes," nodded the janitor, "just about that."
