I stopped behind.

The guests had gone and we were left alone.

Sitting down opposite one another, we lighted our pipes. Silvio was much agitated; no traces of his former gaiety remained. Deadly pale, with sparkling eyes, and a thick smoke issuing from his mouth, he looked like a demon. Several minutes passed before he broke silence.

"Perhaps we shall never meet again," he said. "Before saying good-bye I want to have a few words with you. You may have remarked that I care little for the opinions of others. But I like you, and should be sorry to leave you under a wrong impression."

He paused, and began refilling his pipe. I looked down and was silent.

"You thought it odd," he continued, "that I did not require satisfaction from that drunken maniac. You will grant, however, that being entitled to the choice of weapons I had his life more or less in my hands. I might attribute my tolerance to generosity, but I will not deceive you. If I could have chastised him without the least risk to myself, without the slightest danger to my own life, then I would on no account have forgiven him."

I looked at Silvio with surprise. Such a confession completely upset me. Silvio continued:—

"Precisely so: I had no right to endanger my life. Six years ago I received a slap in the face, and my enemy still lives."

My curiosity was greatly excited.

"Did you not fight him?" I inquired. "Circumstances probably separated you?"
