"Who's he?"

"You haven't heard of Sanford Quest?"

"Never in my life."

The young man whose privilege it was to have been born and lived all his days in New York, drank half a glassful of wine and leaned back in his chair. Words, for a few moments, were an impossibility.

"Sanford Quest," he pronounced at last, "is the greatest master in criminology the world has ever known. He is a magician, a scientist, the Pierpont Morgan of his profession."

"Say, do you mean that he is a detective?"

The New Yorker steadied himself with an effort. Such ignorance was hard to realise-harder still to deal with.
