"I don't remember her at all, sir. Many of the ladies wore wraps when they came in, and her costume would not have been noticeable if she had on a wrap."

The Supreme Intelligence was thoughtful for another few minutes. At last he turned to Mr. Randolph again.

"You are certain there was only one man at that ball dressed as a Burglar?" he asked.

"Yes, thank Heaven," replied Mr. Randolph fervently. "If there'd been another one they might have taken the piano."

The Supreme Intelligence frowned.

"And this girl was dressed like a Western girl?" he asked.

"Yes. A sort of Spirit-of-the-West costume."

"And no other woman there wore such a dress?"

"No," responded Mr. Randolph.

"No," echoed the two detectives.
