"Did you tell Felix of your engagement?" I asked abruptly.
"Yes; I told him all."
"And when did you hear last from Miss Bellin?"
"Some three months ago. It was because she did not reply to my letters that I came back so soon."
"To whom were your letters sent?"
"To her, of course!"
"Care of Felix?" said I, with instinctive suspicion.
"Why, yes," he said, with a sudden frown. "I did not want Mrs. Bellin to know of our engagement, so did not dare to write openly. Felix undertook to deliver the letters."
"He may have undertaken to do so, but," I added forcibly, "he did not."
"Denham!"
