A young man entered in a long black overcoat and soft hat. He looked about him without surprise, but he seemed to note Mr. Horser’s presence with some concern. The man at the table threw down his cards.

“What the devil do you want, Smith?”

“An important despatch from Washington has just arrived, sir. I have brought it up with the codebook.”

“From Washington at this time of the night,” he exclaimed thickly. “Come in here, Smith.”

He raised the curtains leading into a small anteroom, and turned up the electric light. His clerk laid the message down on the table before him.

“Here is the despatch, Mr. Mace,” he said, “and here is the translation.”

“English Ambassador demands immediate explanation of arrest of Duke Souspennier at Waldorf to-night. Reply immediately what charge and evidence. Souspennier naturalised Englishman.”

Mr. Mace sprang to his feet with an oath. He threw aside the curtain which shielded the room from the larger apartment.

“Horser, come here, you damned fool!”

Horser, with a stream of magnificent invectives, obeyed the summons. His host pointed to the message.
