The Great Prince Shan by E. Phillips Oppenheim

The great house in Curzon Street awoke, the following morning, to a state of intense activity. Taxi-cabs and motor-cars were lined along the street; a stream of callers came and went. That part of the establishment of which little was seen by the casual caller, the rooms where half a dozen secretaries conducted an immense correspondence, presided over by Li Wen, was working overtime at full pressure. In his reception room, Prince Shan saw a selected few of the callers, mostly journalists and politicians, to whom Li Wen gave the entree. One visitor even this most astute of secretaries found it hard to place. He took the card in to his master, who glanced at it thoughtfully.

"The Earl of Dorminster," he repeated. "I will see him."
