He is personally a most fearless man, and would be inclined to sweep them away arbitrarily. But, naturally, the police make their own arrangements. In fact, the Premier’s chauffeur, O’Murphy, is a C.I.D. man.”

“O’Murphy? That is a name of Ireland, is it not so?”

“Yes, he is an Irishman.”

“From what part of Ireland?”

“County Clare, I believe.”

“ Tiens! But proceed, milord.”
