His ears were strained. That house was curiously quiet and forbidding. The White Cavalier, whom he had believed to be the notorious Sparrow, had been proved to be one of his assistants. He had now met the real, elusive adventurer, who controlled half the criminal adventurers in Europe, and had found in him a most genial friend. He was there to seek his advice and to act upon it.

As he reflected, he realized that without the aid of The Sparrow he would have long ago been in the hands of the police. So widespread was the organization which The Sparrow controlled that it mattered not in what capital he might be, the paternal hand of protection was placed upon him—in Genoa, in Brussels, in London—anywhere.

Hence his peril of arrest. It was that point which he wished to discuss with the great arch-criminal of Europe.

“Then you know the truth—eh?”
