“What sin have I done?”

“You have sinned by pride, Soradaci, in thinking that I was under an obligation to you for betraying me and giving my letters to the secretary.”

“How shall I expiate this sin?”

“Thus. To-morrow, when Lawrence comes, you must lie on your bed, your face towards the wall, and without the slightest motion or a single glance at Lawrence. If he address you, you must answer, without looking at him, that you could not sleep, and need rest. Do you promise me entirely to do this thing?”

“I will do whatsoever you tell me.”

“Quick, then, take your oath before this holy picture.”

“I promise, Holy Mother of God, that when Lawrence comes I will not look at him, nor stir from my bed.”

“And I, Most Holy Virgin, swear by the bowels of your Divine Son that if I see Soradici move in the least or look towards Lawrence, I will throw myself straightway upon him and strangle him without mercy, to your honour and glory.”

I counted on my threat having at least as much effect upon him as his oath. Nevertheless, as I was anxious to make sure, I asked him if he had anything to say against the oath, and after thinking for a moment he answered that he was quite content with it. Well pleased myself, I gave him something to eat, and told him to go to bed as I needed sleep.

As soon as he was asleep I began to write, and wrote on for two hours. I told Balbi all that had happened, and said that if the work was far enough advanced he need only come above my cell to put the final stroke to it and break through. I made him note that we should set out on the night of the 31st of October, and that we should be four in all, counting his companion and mine. It was now the twenty-eighth of the month.
