"Has anything been heard from your prisoner since this morning?"
"Yes. He asked for pen and ink about one o'clock this afternoon. I went up to see him, to find out why he wanted them. He seemed deeply affected, was almost in tears, and apparently afraid to meet my gaze. He said he wished to write a note, breaking an engagement he had had for this afternoon. He usually had Wednesday afternoons off. I permitted him to write the letter."
Duvall began to show signs of deep interest on hearing this. "Where is it?" he exclaimed.
"What, monsieur?" The Ambassador evidently did not follow him.
"The letter."
"I sent it, of course."
"But you read it first?"
"Yes. It was addressed to a man named Seltz, Oscar Seltz, if I recollect correctly, at a barber shop in Piccadilly Circus, which, as you know, is close by. This fellow Seltz was a friend of Noël's. I have several times heard him speak of him. They were accustomed to spend their afternoons off together, I understand."
"And the note?" asked Duvall, impatiently. "What did it say?"
"Merely that Noël was unable to keep his appointment for that afternoon, and did not expect to see his friend again before his departure. Seltz must have been planning some trip. The letter, as I remember, was quite cool, almost unfriendly in its tone."
