"Yes," I answered.

"What is he?"

"He's a jewel thief."

The two men stared at each other. Then the man at my side rubbed his chin between a meditative thumb and forefinger. He was plainly puzzled. He began to take on human attributes, and he promptly became a less interesting and a less impressive figure. He looked at Alice Churchill and at her brother, and then back at me again.

Then, having once more absently caressed his chin, he swung about and faced the wondering and silent girl who sat opposite him.

"Excuse me, miss, but would you mind answering a question or two?"

It was her brother who spoke before she had time to answer.

"Wait," he interposed. "Just who are you, anyway?"

The man, for answer, lifted the lapel of his coat and exhibited a silver badge.

"Well, what does that mean?" demanded the quite unimpressed youth.
