I was sure that the room below my cell was no other than the one in which I had seen M. Cavalli. I knew that this room was opened every morning, and I felt persuaded that, after I had made my hole, I could easily let myself down with my sheets, which I would make into a rope and fasten to my bed. Once there, I would hide under the table of the court, and in the morning, when the door was opened, I could escape and get to a place of safety before anyone could follow me. I thought it possible that a sentry might be placed in the hall, but my short pike ought to soon rid me of him. The floor might be of double or even of triple thickness, and this thought puzzled me; for in that case how was I to prevent the guard sweeping out the room throughout the two months my work might last. If I forbade them to do so, I might rouse suspicion; all the more as, to free myself of the fleas, I had requested them to sweep out the cell every day, and in sweeping they would soon discover what I was about. I must find some way out of this difficulty. I began by forbidding them to sweep, without giving any reason. A week after, Lawrence asked me why I did so. I told him because of the dust which might make me cough violently and give me some fatal injury. "I will make them water the floor," said he. "That would be worse, Lawrence, for the damp might cause a plethora." In this manner I obtained a week's respite, but at the end of that time the lout gave orders that my cell should be swept. He had the bed carried out into the garret, and on pretence of having the sweeping done with greater care, he lighted a candle. This let me know that the rascal was suspicious of something; but I was crafty enough to take no notice of him, and so far from giving up my plea, I only thought how I could put it on good train. Next morning I pricked my finger and covered my handkerchief with the blood, and then awaited Lawrence in bed. As soon as he came I told him that I had coughed so violently as to break a blood-vessel, which had made me bring up all the blood he saw. "Get me a doctor." The doctor came, ordered me to be bled, and wrote me a prescription. I told him it was Lawrence's fault, as he had persisted in having the room swept. The doctor blamed him for doing so, and just as if I had asked him he told us of a young man who had died from the same cause, and said that there was nothing more dangerous than breathing in dust. Lawrence called all the gods to witness that he had only had the room swept for my sake, and promised it should not happen again. I laughed to myself, for the doctor could not have played his part better if I had given him the word. The guards who were there were delighted, and said they would take care only to sweep the cells of those prisoners who had angered them. When the doctor was gone, Lawrence begged my pardon, and assured me that all the other prisoners were in good health although their cells were swept out regularly.
