The heat being great, Andreuccio, as soon as he found himself alone, stripped to his doublet and putting off his hosen, laid them at the bedhead; after which, natural use soliciting him to rid himself of the overmuch burden of his stomach, he asked the boy where this might be done, who showed him a door in one corner of the room and said, 'Go in there.' Accordingly he opened the door and passing through in all assurance, chanced to set foot on a plank, which, being broken loose from the joist at the opposite end, [flew up] and down they went, plank and man together. God so favoured him that he did himself no hurt in the fall, albeit he fell from some height; but he was all bemired with the ordure whereof the place was full; and in order that you may the better apprehend both that which hath been said and that which ensueth, I will show you how the place lay. There were in a narrow alley, such as we often see between two houses, a pair of rafters laid from one house to another, and thereon sundry boards nailed and the place of session set up; of which boards that which gave way with Andreuccio was one. Finding himself, then, at the bottom of the alley and sore chagrined at the mishap, he fell a-bawling for the boy; but the latter, as soon as he heard him fall, had run to tell his mistress, who hastened to his chamber and searching hurriedly if his clothes were there, found them and with them the money, which, in his mistrust, he still foolishly carried about him. Having now gotten that for which, feigning herself of Palermo and sister to a Perugian, she had set her snare, she took no more reck of him, but hastened to shut the door whereby he had gone out when he fell. Andreuccio, getting no answer from the boy, proceeded to call loudlier, but to no purpose; whereupon, his suspicions being now aroused, he began too late to smoke the cheat. Accordingly, he scrambled over a low wall that shut off the alley from the street, and letting himself down into the road, went up to the door of the house, which he knew very well, and there called long and loud and shook and beat upon it amain, but all in vain. Wherefore, bewailing himself, as one who was now fully aware of his mischance, 'Ah, woe is me!' cried he. 'In how little time have I lost five hundred florins and a sister!' Then, after many other words, he fell again to battering the door and crying out and this he did so long and so lustily that many of the neighbours, being awakened and unable to brook the annoy, arose and one of the courtezan's waiting-women, coming to the window, apparently all sleepy-eyed, said peevishly, 'Who knocketh below there?'
