Inspector Dunbar, closely as he held himself in hand, started slightly.

"Are you sure?"

"Certainly. Before I--when I was younger--I traveled in the East, and I
know the voice and intonation of the cultured Oriental."

"Can you place him any closer than that?"

"No, I can't venture to do so." Brian's manner was becoming,
momentarily, more nearly that of a gentleman. "I might be leading you
astray if I ventured a guess, but if you asked me to do so, I should say
he was a Chinaman."

"A CHINAMAN?" Dunbar's voice rose excitedly.

"I think so."

"What occurred next?"

"I turned my cab and drove off out of the Square."

"Did you see where the man went?"

"I didn't. I saw nothing of him beyond his hand."

"And his hand?"

"He wore a glove."
