Her name was Henrietta Lacks, but scientists know her as HeLa. She was a poor Southern tobacco farmer who worked the same land as her slave ancestors, yet her cells - taken without her knowledge - became one of the most important tools in medicine: The first “immortal” human cells grown in culture, which are still alive today, though she has been dead for more than 60 years. HeLa cells were vital for developing the polio vaccine; uncovered secrets of cancer, viruses, and the atom bomb’s effects.

Detective Pia Kirchhoff is about to set off on a long-delayed honeymoon when she receives a phone call. An elderly woman has been shot and killed while walking her dog. A short while later, another murder is committed, and the modus operandi is eerily similar: A woman is killed by a bullet that smashes through her kitchen window - and in both cases the same weapon fired the shot. Two more murders follow in short order. None of the victims had enemies, and no one knows why they were singled out.
