 What can be inferred about the personality of Grannie Annie from the passage?
DOUBLE TROUBLE by CARL JACOBI Grannie Annie, that waspish science-fiction writer, was in a jam again. What with red-spot fever, talking cockatoos and flagpole trees, I was running in circles—especially since Grannie became twins every now and then. Grannie Annie strode in the lead, her absurd long-skirted black dress looking as out of place in this desert as the trees. As we reached the first of those trees, Grannie came to a halt. He could be excused this time, however, for this was only our third day on Jupiter's Eighth Moon, and the country was still strange to us. When Annabella C. Flowers, that renowned writer of science fiction, visiphoned me at Crater City, Mars, to meet her here, I had thought she was crazy. But Miss Flowers, known to her friends as Grannie Annie, had always been mildly crazy. If you haven't read her books, you've missed something. Blood-and-thunder as these books are, however, they have one redeeming feature—authenticity of background. Grannie Annie was the original research digger-upper, and when she laid the setting of a yarn on a star of the sixth magnitude, only a transportation-velocity of less than light could prevent her from visiting her "stage" in person. He was an old prospector Grannie had met, and he had become so attached to the authoress he now followed her wherever she went. So now here we were at the outer reaches of the Baldric, four travelers on foot with only the barest necessities in the way of equipment and supplies. And then all at once Grannie stopped again, this time at the top of a high ridge. The duplicate of myself was talking to the duplicate of Grannie Annie, and she was replying in the most natural way. As that dot continued to move across the heavens in a single direction, I called Grannie's attention to it. She offered no further explanation, but a quarter of an hour later as we topped another rise a curious elliptical car with a long slanting windscreen came into view. Five minutes later Grannie was shaking his hand vigorously and mumbling introductions. "I can't tell you how glad I am you're here, Grannie," he said. Apparently these adjustments moved planes or fins on the kite and accounted for the car's ability to move in any direction. "But surely you must have some idea of where they go," Grannie said.
 She's fearless and quick-witted
