Franziska can't believe it. That her brother Georg died in a hit-and-run accident is shocking enough; but her sister-in-law insists it was murder. Who would want to kill Georg, a mechanic for an airplane maintenance company? While investigating on her own, she finds clues pointing to foul play. And in public prosecutor Treptow, she finds a sympathetic ear and a promise of help. But Franziska is too hot-headed to wait for the unwieldy legal machine to begin its work. She wants results, now, within or without the ambit of the law.
