but I don't know the man

Just before I reached the landing I saw his door opened from the inside--a long, delicate, nervous hand (not my friend's hand certainly) held it ajar. At the same time I heard Pesca's voice saying eagerly, in low tones, and in his own language--"I remember the name, but I don't know the man. You saw at the Opera he was so changed that I could not recognise him. I will forward the report--I can do no more." "No more need be done," answered the second voice. The door opened wide, and the light-haired man with the scar on his cheek--the man I had seen following Count Fosco's cab a week before--came out. He bowed as I drew aside to let him pass--his face was fearfully pale--and he held fast by the banisters as he descended the stairs. I pushed open the door and entered Pesca's room. He was crouched up, in the strangest manner, in a corner of the sofa. He seemed to shrink from me when I approached him. "Am I disturbing you?" I asked. "I did not know you had a friend with you till I saw him come out." "No friend," said Pesca eagerly. "I see him to-day for the first time and the last." "I am afraid he has brought you bad news?" "Horrible news, Walter! Let us go back to London--I don't want to stop here--I am sorry I ever came. The misfortunes of my youth are very hard upon me," he said, turning his face to the wall, "very hard upon me in my later time. I try to forget them--and they will not forget ME!" "We can't return, I am afraid, before the afternoon," I replied. "Would you like to come out with me in the meantime?" "No, my friend, I will wait here. But let us go back to-day--pray let us go back." I left him with the assurance that he should leave Paris that afternoon. We had arranged the evening before to ascend the Cathedral of Notre Dame, with Victor Hugo's noble romance for our guide. There was nothing in the French capital that I was more anxious to see, and I departed by myself for the church. Approaching Notre Dame by the river-side, I passed on my way the terrible dead-house of Paris--the Morgue.
