PI Beer Henning arrives on a prestigious Lowveld rose farm. There he discovers pitch-black roses that hide a deadly secret: the devil’s flower, the perfect murder weapon.
He meets the eccentric owner of the farm, Mathilda van Eck, whose seventeen-year-old son Marnus died exactly a year ago, under suspicious circumstances. She hires Beer to find out what really happened. Beer suspects that Marnus was murdered . . . And to boot, he’s convinced the killer is still on the farm!
