Count Olaf visited her at the carnival whenever he needed to know the latest whereabouts of the Baudelaires, believing that she could tell through psychic means. However, Madame Lulu wasn't a real psychic. Instead, she requested her guests to close their eyes, then researched the answers to their questions, using the documents in an entire archival library hidden under a table in her tent. A device that she invented would trick her guests into thinking that smoke and lightning would initiate inside the tent. It is unknown whether or not Count Olaf realized that she was a fraud.
