Even though she's only been viewed as a cardboard cutout, it's unknown if Patty's really fictional or not. We don't know the actually name of the author who wrote the novels, but it's possible that the author's name had to be made up in order to stay hidden from all the eyes and ears who could be following her every move. In fact, this should be mentioned that Patty Persimmon made herself unknown to the Berry Bitty World because she had to go incognito to avoid being seen by not-so-friendly faces who will likely eliminate her at any cost. This situation is so similar to Daring Do from MLP:FIM because she wrote her novels under the name R.K. Yearling to avoid suspicion. So, maybe Patty Persimmon is the author herself! Which means that every book she's written could be based on the real mysteries she's solved, so her current home is located somewhere between the boundaries of Berry Bitty City and Berry Big City!
