To obviate unnecessary repetition I shall give the result of my inquiries as I related it to Quarles and Zena when I went to Chelsea that night.

"You look satisfied and successful, Wigan," said the professor.

"I am both," I answered. "Whether we shall catch the actual criminal is another matter. We may at least lay our hands on one of his accomplices. Will it surprise you to learn that I am having the Italian Masini carefully watched?"

"It is a wise precaution."

"I am inclined to adopt the method you do sometimes, professor, and begin at the end," I went on. "First, as regards Mr. Bridwell's parliamentary friends and acquaintances, and his political career. Although he is a Member whose voice is not often heard in the House, his intimate knowledge of Europe, its general history and politics, gives him importance. He is constantly consulted by the Government, and his opinion is always considered valuable. His colleagues are unanimous on this point, and generally he seems to be respected."

"But the respect is not unanimous, you mean?"

"It is not."

"And in his private life?"

"I have not found any one who was intimate with him in private."

"I see; kept politics and his private life entirely separate," said Quarles.
