William Le Queux,
The Stretton Street Affair — Chapter 24
(1922)
“ The valet’s story I did not doubt. I knew that such men as the late Baron were often compelled, in their own interests, to receive visits from mysterious and often undesirable persons, most of whom were paid for their information. Every giant of finance employs his secret agents, whose duty it is to keep his principal informed of the various political and other secrets in Europe. Indeed, the great financiers know more of the underground currents of foreign politics than they do at any Embassy or Ministry of Foreign Affairs. ”
