"Have you any letters to go?"
"No, Doughty."
"But there's the Castle bag, sir. I want the letters out of that."
"True; thank you for reminding me of them." He opened the door. "Here is the key." He handed it through the door, adding: "I am most particularly engaged. Let no one come to me."
He retired from the door feebly. He went back to the fire and sat down.
In half an hour he rang his bell. The porter entered.
"Are the letters posted?"
"Yes, sir."
"All gone?"
"Yes, sir."
