Catella, hearing this, without anywise considering who it was that said it to her or suspecting his design, forthright, after the wont of jealous folk, gave credence to his words and fell a-fitting to his story certain things that had already befallen; then, fired with sudden anger, she answered that she would certainly do as he counselled,--it was no such great matter,--and that assuredly, if Filippello came thither, she would do him such a shame that it should still recur to his mind, as often as he saw a woman. Ricciardo, well pleased at this and himseeming his device was a good one and in a fair way of success, confirmed her in her purpose with many other words and strengthened her belief in his story, praying her, natheless, never to say that she had heard it from him, the which she promised him on her troth. Next morning, Ricciardo betook himself to a good woman, who kept the bagnio he had named to Catella, and telling her what he purposed to do, prayed her to further him therein as most she might. The good woman, who was much beholden to him, answered that she would well and agreed with him what she should do and say. Now in the house where the bagnio was she had a very dark chamber, for that no window gave thereon by which the light might enter. This chamber she made ready and spread a bed there, as best she might, wherein Ricciardo, as soon as he had dined, laid himself and proceeded to await Catella. The latter, having heard Ricciardo's words and giving more credence thereto than behoved her, returned in the evening, full of despite, to her house, whither Filippello also returned and being by chance full of other thought, maybe did not show her his usual fondness. When she saw this, her suspicions rose yet higher and she said in herself, 'Forsooth, his mind is occupied with yonder lady with whom he thinketh to take his pleasure to-morrow; but of a surety this shall not come to pass.' An in this thought she abode well nigh all that night, considering how she should bespeak him, whenas she should be with him [in the bagnio].
